How to start up the slurry pump


The initial starting sequence detailed is intended to bring the system up to operating condition safely with minimal effort. Following those instructions and this simple checklist will have the pumps on line quickly:

1. Verify that all guards, piping, and instrument connections are properly installed and tightened.

2. Open the suction valve completely and verify there are no obstructions in the suction flow.

3. Fill the sump and system as full as possible. The sump should be at operating level but must be at least above the level of minimum suction head (NPSHR) required by the slurry pump.
  • If mechanical seals are used, the pump cavity must have fluid at least above the top of the suction line. If equipped, turn on flush or cooling supply valves.
  • For stuffing boxes, turn on the gland water supply. Verify flow and pressure are in accordance with the Excellence Maintenance Manual and water is dripping from the gland.
  • Never start or run the pump with zero flow!
  • Turn on any cooling water or fans for other equipment.

4. Close the discharge valve.
  • For vertical discharge pumps or systems with air in the discharge piping, open the discharge valve an inch or two (25 – 50 mm) before starting. This will let the air bleed out as the pump comes up to speed.
  • Do not open the valve past 25% or the pump could rotate in reverse during backflow.

5. Check that all personnel and loose items are clear of the pump and rotating elements.

6. Jog the motor to verify that pump rotation is correct.

7. Start the motor. The pump should reach operating speed in just a few seconds.

8. As the pump reaches operating speed, fully open the discharge valve.
Do not allow the pump to operate with the valve closed as there is a danger of steam generation and explosion!

9. Inspect the pump and drive components for any leaks or unusual vibrations.
After the pumps have been operating and the system is full, the pumps can be stopped by closing the discharge valve as the pump is shut off. This will reduce backflow potential in the system.

Investors pour into gold stocks: Barrick gains $7bn in 7 weeks


The gold price made a serious attempt to scale the psychologically important $1,400 level on Friday, sending investors scurrying for gold mining stocks.
Bullion bulls are celebrating an 18% jump in the price of gold since the metal hit multi-year lows below $1,200 at the end of June.
Barrick Gold Corp (TSX:ABX) gained 3% to $21.20 on Friday, up an astounding 49% in just seven weeks.
The Toronto-based global number one gold miner continues to recover from 21-year lows of $14.22 struck on July 5, following a string of setbacks at the company.
Barrick is now worth $21 billion on the TSX, gaining $7 billion in market value in as many weeks. The company, which has written down the value of its assets by some $13 billion this year, peaked at a market capitalization in January 2011 of more than $54 billion.
Gains for Newmont Mining Corp (NYSE:NEM) have been more modest, but the $16.4 billion Denver-based company which hopes to mine around 5 million ounces this year is still up nearly 20% since gold's June 28 low.
The world's third largest gold producer in terms of ounces mine behind Newmont, AngloGold Ashanti (NYSE:AU) gained 3.3% on Friday, but the Johannesburg-based company has made few strides on the back of the resurgent gold price.
Shares of company are still down a 45% year to date as it struggles with unrest in the its home country's mining sector and falling gold output. In dollar terms Anglogold's JSE-listed shares have performed even worse, down 10% as the rand continues to slide against the US and Canadian dollar.
SEE ALSO: Friday rally sets up gold price breakout
Fellow South African miner Gold Fields' (NYSE:GFI) was the lone counter in the red on Friday as the company suffered a second day of losses in reaction to its purchase of three Barrick gold mines.
Gold Fields acquisition in Australia will add more than 400,000 to its annual output, putting it within range of the mined ounces of Canada's Goldcorp (TSX:G) which expects to produce between 2.5 million and 2.8 million ounces in 2013.
Vancouver-based Goldcorp, the world's most valuable listed gold company, added 2.4% on Friday, pushing its market value to $26.6 billion.
Goldcorp is the best performer of the gold majors, keeping its 2013 market value losses to 10% despite the 16% drop in the gold price this year.
Canadian peer Kinross Gold (TSX:K) – which this year expects to produce between 2.4 million to 2.6 million ounces – traded up more than 3%.
Australia's Newcrest Mining (ASX:NCM) jumped more than 5% on the Sydney bourse.
The 2 million to 2.3 muillion ounce producer is still 43% cheaper than at the start of the year after suffering $6 billion in writedowns, a dividend cut and an investigation by Australian market regulators prompted by suspicious price movements.


Mining company Taseko criticizes lengthy review of gold-copper project


The company behind a proposal to develop a billion-dollar gold and copper mine in the British Columbia Interior lashed out at critics Friday in its parting words to a federal review panel, as well as at the long process that has already seen the mine rejected once by the federal government.
In a written argument filed ahead of the final day of hearings on Friday, the lawyer for Taseko Mines Ltd. said panel members have been misled about the mine proposed 550 kilometres northeast of Vancouver.
“There is no doubt that a great deal of misinformation was the product of an organized campaign designed not to inform the panel’s decision, but calculated to stop the project from proceeding,” said the submission to the Canadian Environmental Assessment Agency panel that spent the previous five weeks holding hearings in surrounding communities.
“Taseko believes that opponents to the mine in aboriginal communities have used culture and heritage inappropriately as a weapon by exaggerating the value of the areas that will be impacted by the mine and their use of those particular lands and resources for cultural purposes.”
The company said it also has “fundamental concerns about fairness of process” because of repeated breaches of panel procedures.
The company repeatedly criticized a previous federal environmental review panel whose report led the environment minister in 2010 to reject a previous plan to develop the deposit that would have destroyed a lake of significance to area First Nations.
“Taseko did what it was asked to do by modifying the proposed project in very substantial ways to address the concerns identified by the previous panel, and despite the fact that Taseko believes that several of those concerns were not based on a proper application of the relevant criteria,” the company said to the latest panel.
The deposit is the 10th-largest undeveloped gold-copper deposit in the world – at least nine million wedding rings’ worth – and for half a century since its discovery, it has remained buried among the pristine lakes and mountains of B.C.’s wild Chilcotin region.
Estimates indicate 2.4 billion kilograms of copper and about 377,000 kilograms (13.3 million ounces) of gold are at the site. The company estimates the mine would generate 550 direct jobs and $340-million in gross domestic product annually.
Opponents – including some First Nations groups, members of the public and groups including Amnesty International and Mining Watch Canada – said the risks to the environment, First Nations culture and wildlife outweigh the rewards.
“The cultural impacts of the project alone are significant, immitigable and of tremendous consequence for the long-term mental and physical health of the Tsilhqot’in communities and the survival of the distinctive way of life that they have maintained through generations of resolute commitment and sacrifice,” the Tsilhqot’in National Government told the panel in its final submission.
The plan to preserve Fish Lake – Teztan Biny to them – is unproven, they said.
Although First Nations have been the most vocal opponents, it’s not an issue of aboriginal versus non-aboriginal, said David Richardson of the Fish Lake Alliance, in a statement filed with the panel ahead of final submissions on Friday.
“We think many residents of the Cariboo have bought into a hollow promise of economic prosperity based on exaggerated rhetoric,” he wrote. “The group that would benefit most if this mine is developed would be distant shareholders and not local stakeholders.”
The main issue remains the long-term survival of Fish Lake, which originally would have been drained for use as a tailings pond.
Taseko said it can prevent contamination from groundwater seepage from a tailings pond now to be located several kilometres away.
Submissions to the panel showed no small amount of support, from councils in the surrounding communities of Williams Lake, 100 Mile House and Quesnel to the area’s Liberal member of the provincial legislature.
“Without an approval for Prosperity Mine, the future of the Cariboo-Chilcotin is bleak,” MLA Donna Barnett said in a letter filed with the panel. She referred the devastation wreaked by the mountain pine beetle on forestry, the crux of the local economy.
“Lobbyists that oppose resource development are just that – lobbyists – who are opposed to everything,” Ms. Barnett wrote.

Kirkland Q1 output down 3% q-o-q owing to planned shutdowns


Gold miner and explorer Kirkland Lake Gold produced 30 316 oz of gold in the three months ended July – the first quarter of its 2014 financial year.
Output was down slightly on the 31 503 oz produced in the previous quarter, but 74% higher than the 17 396 oz produced in the first quarter of the 2013 financial year.
The company produced 97 788 t of ore at a head grade of 0.3246 oz/t. The ore tonnage produced was a quarterly record, as was the average daily ore tonnage rate of 1 063 t.
Kirkland Lake stated that, despite the record ore tonnage rates, production for the quarter was impacted on by a number of planned shutdowns related to the work needed to increase the average mine hoisting capacity to 2 200 t a day, as well as to increase the capacity of the processing plant.
Work undertaken during the quarter included replacing the 10 t skips with 12.5 t skips, as well as work to optimise the existing mill grinding circuit and to bring the new crushing circuit on line.
The estimated impact of these shutdowns was two to three weeks of normal production over the quarter, which was slightly longer than expected. As a result, the production tonnage was 4.6% under planned production for the quarter.
Kirkland Lake warned that its processing plant would be impacted on by several more planned shutdowns throughout the 2014 financial year, as new equipment is brought on line.
The shutdowns were likely to affect the timing of production, but the gold miner was confident that it would not impact on overall production, with the company’s output guidance for the full year remaining at between 150 000 oz and 180 000 oz of gold.
Production is planned to increase quarterly over the course of the year, but the rate at which this occurs will be dependent on the rate at which the critical path activities are completed.

Carpathian Gold deal shows how every drop is squeezed out of juniors


Carpathian Gold (TSE:CPN) managed to rake in the cash it said in June it needed to complete construction if its 100% owned Riacho dos Machados gold mine in Brazil.
Given the tough financing environment for juniors, those developing gold projects in particular, for Carpathian to secure the final $19 million to start pouring as early as next month seemed like something of a victory.
But the details of the deal and investors' reaction to it show just how harsh the realities of junior mining has become.
All the bad news were supposed to have been baked into Carpathian's stock price already.
The Toronto company in June let the market know costs are going up and expected production for this year is going down and was duly punished for it.
Yesterday's deal saw the counter take another gap down on very heavy volumes crashing 26%.
Not entirely surprising considering the bought deal financing was concluded at a price that much below the ruling price.
Comparing yesterday's private placement with a similar deal done in November 2011 which was led by the same parties – Cormark Securities and Macquarie Capital Markets – shows just how much things have changed.
Now: $16 million plus $3.4 million option at 14c vs 19c the day before the announcement.
Then: $46 million at 40c vs 46c before the announcement.
The discount has doubled.
It's not as if RDM is not an attractive asset. $176 million gets you 100,000oz for eight years at cash costs of $560 according to the company.
But these days that just isn't good enough.
As an aside, in July 2011, Carpathian also raised $20 million from none other than Barrick Gold for a project in Romania. Barrick stumped 52c per Carpathian share at the time.
But those were very different days indeed, especially for Barrick.

New Prosperity mine hearings wrap up in B.C.


Public hearings for acontroversial open pit gold and copper minenear Williams Lake are wrapping up this week.
The federal government is reviewing Taseko's New Prosperity mine proposal for the second time. Ottawa rejected the project in 2010 over concerns the mine would destroy nearby Fish Lake.
  • B.C. mine proposal public hearings draw hundreds
  • First Nation seeks own hearing on New Prosperity mine
The new proposal will no longer turn the lake into a tailings pond.
But UBC fisheries professor John Stockner told the panel the mine will destroy a large portion of the lake's wetlands, ultimately killing the fish.
"Fairly soon, the impact will roughly destroy 40 to 50 per cent of the wetlands that drain into the system, and its productivity is completely based upon on what happens in its drainage,” he said.
"The amount of organic production in the lake will settle to the bottom, and the fish — within a decade, maybe two — will be asphyxiated one cold, February night. The oxygen will be depleted, and fish, like us, require oxygen.”

'We need this mine'

The panel also heard from project proponents, who maintain there will be a minimal impact to the environment.
Supporters also spoke about the project’s economic benefits. Taseko claims the mine will create about 700 direct jobs, and $10 billion in revenue over the mine’s 20-year life span.
"We need this mine,” said John Meech, professor of mining engineering at UBC.
“It's one of the top 10 copper-gold ore bodies in the world. And the question isn't should we mine, but when will we mine?"
The final community hearing is today in Dog Creek. Final remarks are on Friday in Williams Lake.
The federal government is expected to make a decision on the project some time this year.

Harper unveils aboriginal mining grant in northern Canada


S‎tephen Harper is trumpeting a federal grant to teach essential mining skills to 400 aboriginal workers in the Northwest Territories and Nunavut, an effort to ensure the local population benefits from big resource extraction projects.
The Prime Minister’s annual summer tour of northern Canada coincides with a controversy in neighbouring Yukon over a new territorial government effort to import foreign workers for industries such as mining.
The $5.8-million over two years will finance a 25-month ‎program delivered with the Northwest Territories Mine Training Society for participants in the NWT and the Kitikmeot region of Nunavut.
“The North’s rapidly growing extractive industry is driving prosperity and creating demand for local skilled workers,” Mr. Harper said on Tuesday. “The support being provided today will help aboriginal participants in the North gain the training they need to access the jobs and prosperity being generated by the industry’s growth.”
‎The training is taking place in 11 communities and on three mine sites across the Territories and the Kitikmeot region of ‎Nunavut, including Hay River. After the training, six local employer partners, including three area mines, will place graduates into jobs.
‎‎The Prime Minister announced the funds during a stop in Hay River, NWT, on the third day of his 2013 summer tour of northern Canad‎a.‎ Mr. Harper began his eighth annual northern tour of Canada on Sunday, embarking on a six-day trip that started in Yukon and crosses the Arctic Circle to promote mining and other resource extraction in this country’s most sparsely populated region.
Like Progressive Conservative chief John Diefenbaker, Mr. Harper has a use-it-or-lose it attitude toward northern Canada that in the early years of his government led to high-profile measures to promote Canadian sovereignty in the resource-rich Arctic.
Now in his eighth year in office, the Prime Minister is focusing more on economic and social development of a region that struggles with unemployment and the challenge of creating durable jobs.
Mr. Harper’s other stops include Gjoa Haven and Rankin Inlet in Nunavut as well as Raglan Mine, the location of a massive nickel mining complex in northern Quebec.
Training will also be delivered at three mine sites in the Territories: Diavik Diamond Mine, Snap Lake Mine and Ekati Diamond Mine.


Gold, silver samples light fire under Cache Exploration


Micro-cap Cache Exploration Inc (CVE:CAY) tripled on Tuesday after samples from its BC gold-silver-copper project persuaded investors to make the share one of the most active stocks on the Toronto Venture Exchange.

By early afternoon the Toronto-based junior was trading up 200% at $0.045 on the Toronto big board, off its morning highs when shareholders enjoyed a more than four-fold return.
Around 3.3 million shares in the company which only has 24 million shares outstanding, had changed hands by 1:30 pm EST compared to the daily average of just 55,000. The counter – better known for its rare earth exploration activity – has made huge gains in 2013 – it is up 80% year to date.

Yesterday Cache released grab sampling results on its 100% owned Quinn Eskay gold-silver-copper property north of Stewart in the Stewart-Skeena mining district in British Columbia where it owns 8,400 acres.

Highlights from the vein grab sampling included 8.18 grams per tonne gold, 87.5 grams per tonne silver and 0.28% copper with quantities of lead and zinc also present, and chips from another outcrop boasting 1.26 grams per tonne gold, 151.0 grams per tonne silver and 6.78% lead.

A Comparison of Cooling Systems for High Pressure Pumps


When operating a high pressure pump for waterjet cutting, it is crucial to run a reliable cooling system as some vital components of the pump may be damaged if the temperature of the hydraulic oil rises above a certain point. Therefore, KMT Waterjet pumps carry out an automatic shut-down as soon as the oil gets too hot. For its pumps, KMT recommends an operating temperature of 40-45°C (104-113°F).
Concerning the cooling system, the company offers a few alternatives: Water cooler, air cooler or a combination of both. Which of these alternatives is the best one depends on the installation parameters of each individual installation.

Functional Principles of the different Cooling Systems
Models with a water cooler introduce the cooling water through a connection on the rear bulkhead of the machine. A solenoid valve in the outlet line regulates the cooling flow, which is sustained by a recirculation pump, through the heat exchanger. The plate style design allows cooling water and oil to flow side by side through alternating plates. The cooled oil then passes through the filter element and returns to the reservoir. The cooling water is either discharged or routed to a water chiller.The air cooler works as follows: The recirculation pump pulls oil from the hydraulic oil reservoir and sends it to the external heat exchanger. A temperature switch mounted on the reservoir monitors the oil temperature and regulates the air flow to the heat exchanger through a signal to the control panel to initiate power to the fan. Both systems feature a dual scale level/temperature sight gauge on the side of the reservoir to visually monitor the oil temperature.

To answer the question which of the alternative cooling systems is suitable for a particular application, environmental influences as well as the installation conditions have to be taken into consideration. Basically, the air cooler only works reliably up to an ambient temperature of about 30°C (86°F): For the efficient operation of such a system, the ambient temperature has to be at least 10°C (50°F) cooler than the temperature of the hydraulic oil. If the thermometer rises above this value, the cooling power decreases rapidly. Indeed, the pump still runs at higher temperatures – the automatic shut-down does not occur until the oil reaches 62°C (144°F); however, exceeding the recommended maximum temperature may have a negative effect on the lifetime of the high pressure seals in the intensifier.

Advantages of the Air Cooler
Anyway, the air cooler has its advantages, too. The water cooler as the standard option for KMT STREAMLINE pumps may be slightly cheaper in the initial purchase, however, this price advantage is quickly put into perspective: If a water cooler is installed without an additional chiller for the cooling water, further operating expenses are incurred as the water directly goes to the drain after one turn in the cooling circuit,. A 50 hp pump for example can have a cooling water consumption of 10 l/min. Depending on water costs and running times, the system creates operational costs which can be avoided using an air cooler. These costs can be saved by reusing the water. To do so, the machine operator has to connect an external chiller to cool down the used water before reintroducing it into the cooling circuit. Yet, the costs for such a chiller may actually amount to three times the additional costs of the air cooler. So considering the total costs, the air cooler is the more cost-effective alternative after all.

Regarding the installation effort, the air cooler also comes out front. This option provides the buyer with a ready-to-use system. In contrast, installing the water cooler necessitates either a set-up of the chiller or of the drain for the cooling water. So an air cooler is particularly advantageous for smaller companies which have no access to an already existing cooling system. Additionally, the exit air from the air cooler can be used to heat up small buildings.

Advantages of the Water Cooler
A water cooler may pay off in case the machine operator can dispose of cheap water, for example a river or some other water bodies close to the location of the installation. Additional costs still cannot be completely avoided though: When feeding the water cooler via a body of flowing or standing water, an additional pump probably becomes necessary to reach the minimum inlet water pressure of 2.5 bar.

However, in regions regularly and permanently reaching 30°C (86°F) ambient temperature or more, there is no alternative to a water cooler as the functionality of an air cooler meets its natural limitations. The same is true for large pump networks consisting of 4 to 5 or more machines. If air coolers are used in such cases, they will create air turbulences which may be more or less strong depending on the type of building and which delimit the cooling system’s efficiency. Additionally, the large amount of exit air created by the many systems heats up the environment and makes a cooling down just with air impossible.

What’s the best System?
To put it in a nutshell, the air cooler is the more cost-effective alternative compared to the water cooler regarding purchasing and operating costs, but it cannot be used in every circumstance. For high average ambient temperatures or large pump networks, water coolers are the more reliable option. The highest flexibility though is achieved with a combination system as KMT offers for its high pressure slurry pumps. Particularly in regions with occasional temperature peaks of above 30°C (86°F), the cost-effective air cooler can be combined with the more reliable water cooler. In such a combination system, the air cooler is the main cooling system and the water cooler is switched on only if needed.

Magnetic drive pumps are a centrifugal slurry pump in which the motor is coupled to the pump by magnetic technology rather than by a mechanical shaft. The pump consists of three main parts: the driving magnet, the driven magnet, and the magnet cup.

The driving magnet is connected to the motor and is radially aligned with the driven magnet, the latter of which is connected to the pump. The magnets are separated by the magnet cup, which acts as a static barrier between the two and seals the pumped fluid from the atmosphere, resulting in a ‘seal-less’ (sans mechanical seal) design. This barrier is also referred to as a hermetic seal. The driving magnet rotates as power is applied to the motor and the driven magnet follows suit, compelled by magnetic attraction.

This pump type has been available for several years. Mag drive pumps have recently become more popular due to recent advancements in magnet technology combined with more stringent application requirements, the incompetence of mechanical seals, and new legislation regarding fugitive emissions.

Magnetic drive pumps provide several benefits:
  • Seal-less design: No mechanical seal is required
  • Zero leakage / 100% emissions free
  • High reliability/ lower maintenance
  • Safer operations pumping hazardous fluids
These advantages are the primary reason why more slurry pump users are turning to mag drive pumps. Their increased reliability and lower total cost of ownership have also contributed to an increased demand for the pumps over more conventional options. Highly reliable and safe to operate, magnetic drive pumps are the best choice for handling hazardous and expensive fluids in a variety of applications.

Maudore inks milling agreement with Abcourt Mines


Quebec-based Maudore Minerals on Friday announced a custom-milling agreement between its subsidiary, Aurbec Mines, and gold miner Abcourt Mines to treat ore from the Elder mine at Aurec’s Sleeping Giant mill.
The Elder mine is located near Rouyn-Noranda, Quebec, and the ore would be trucked to Aurbec's mill, located about 80 km north of Amos, Quebec. The six-month agreement could be if both parties agree desired to do so.
Aurbec had applied for environmental permits and authorisations to store and process the Elder mineralised material at Sleeping Giant and a certificate of authorization was expected soon, after which ore shipments would start.
Maudore had acquired the Sleeping Giant gold mill and adjacent tailings facility through acquiring a subsidiary of North American Palladium for $18-million in cash and 1.5-million common shares in March.

Titan Proposes Acquisition of Additional Copper Project in Katanga Province, DRC


Titan Goldworx Resources Inc. ("Titan" or the "Company") (CNSX:TTN) is pleased to announce that further to its press release dated May 31, 2013, it has amended the Letter of Intent with Falcon Copper Ltd. ("Falcon") to include Titan's proposed acquisition from Falcon of an additional copper project located in the Democratic Republic of the Congo (DRC) (the "Amendment").
The Amendment provides Titan with the opportunity to acquire from Falcon a 95% interest in PR12116 (the "Kimano Concession") a copper exploration and development project that was subject to significant exploration activities by a leading global mining company from 2003 until 2009. Along with Titan's previously announced transaction for the Katambo copper project ("Katambo Concession") in DRC, the Kimano Concession represents the Company's second project in a growing portfolio of copper projects being developed by Titan.
About the Kimano Concession
The Kimano Concession is located approximately 20km west of the Kinsevere copper mine, owned by China's Minmetals Resources. Previous work on the Kimano Concession indicates demonstrated areas with combinations of high geochemical values (up to 395ppm Cu), geophysical anomalies and fault intersections. Five target areas have been identified based on the historical data and Titan intends to execute, within the next 60 days, an advanced exploration program including RC and diamond drilling campaigns on certain of the targets. The exploration and drilling programs will be jointly managed by Titan and Falcon with the goal of defining an initial resource as soon as possible on the Kimano Concession. Subject to Titan's due diligence and receipt of satisfactory results from the exploration and drilling program, Titan shall have the exclusive right to acquire from Falcon a 95% interest in the Kimano Concession.
The completion of the transaction is subject to a number of conditions, including but not limited to the execution of a definitive agreement, completion of satisfactory due diligence, completion of a National Instrument 43-101 compliant technical report, and approval of the transaction by the board of directors of Titan and Falcon. There can be no assurance that the transaction will be completed as proposed, or at all.
Titan's Strategic Development
Titan's objective is the consolidation and development of copper projects with near-term visibility to production. The Company leverages its own technical and financial expertise and that of its global partners to systematically select and develop those projects that provide a high probability of near-term cash flow. The Company's focus on high value projects with potential for near term production has enabled Titan to engage in discussions with global commodity traders that are actively seeking off-take arrangements within the regions that Titan is currently active. Titan will continue to engage potential off-take partners with a view to forming strategic relationships throughout the project development cycle.
