Resilience is What Makes Miners Successful

The cover of this month’s E&MJ is somewhat deceptive. Yes, it’s a beautiful photo of Yukon Zinc’s Wolverine mine and it looks like a great place for a miners picnic. Nine months out of the year, however, one probably wouldn’t want to be standing in that location without a parka. Working in the Canadian North (Yukon, Nunavut and the Northwest Territories), which is way north for most North Americans, has to be one of the most difficult places to earn a living.

Canada’s North holds an incredible amount of mineral wealth. Operating in harsh arctic conditions requires precision, not only for financial concerns, but more importantly personal wellbeing and safety. Add to that, variables such as a lack of skilled labor, complications related to short operating seasons and a lack of infrastructure, and one wonders why modern day miners pursue these deposits......... read more

Vale Idles Three Pellet Plants
Vale reported in early October 2012 that an additional portion of its iron ore production in Brazil will be allocated to increase the supply of sinter feed, consequently reducing the availability of pellet feed for its pelletizing operations. As a result, the company is temporarily suspending operations at its São Luís and Tubarão I and II pellet plants, located in the states of Maranhão and Espírito Santo, respectively. These plants produced 4.926 million mt of pellets during the first half of 2012, accounting for…… read more

Palmer: Swan and Gillard Killing Mining Investment
Mining executive Professor Clive Palmer has slammed Prime Minister Julia Gillard and Treasurer Wayne Swan for imposing a mining tax that has failed to raise revenue and only managed to kill investment in Australia’s resources sector. Professor Palmer said the Minerals Resource Rent Tax (MRRT) has so far in 2012-13 not raised a cent highlighted the damage the government has caused to the nation’s economy for zero gain. "The MRRT has killed investment in Australian mining and it has also destroyed Australia’s role in mining…. read more

Fleet Operators Ready to Gas Up
The natural-gas production boom in North America and elsewhere has flared miningindustry interest in switching mobile equipment to LNG power

By Russell A. Carter, Managing Editor

In the era before off-road diesel engine emissions became a point of intense focus for regulatory agencies, fuel choices for large, production-fleet mining equipment were relatively simple for mine operators— mainly, "Do you have diesel, what does it cost, and when can you deliver?" Even after the U.S. Environmental Protection Agency’s early off-road diesel emissions standards and their European Union counterparts came into effect in the mid-1990s, operators’ fuel concerns remained largely the same—quantity, availability……. read more

The Benefits of Using Gravity
The leading suppliers offer their outlook on the current state of gravity-separation technology

By Simon Walker, European Editor

With the possible exception of visual sorting—"this one’s green, this one’s not," or however the Bronze Age equivalent ran—being able to separate minerals using differences in their density is the most ancient mineral-processing technique known to man. It is, after all, emulating the natural processes that formed the alluvial deposits in which gold and other dense minerals such as cassiterite were first found and, because of its effectiveness, it still plays a valuable role in a variety of modern mineral-recovery circuits. Panning and vanning, later upgraded by mechanization into shaking tables and jigs, formed the main means of.... read more

Pneumatic Flotation Challenges Conventional Technology
A wide range of bubble sizes, online control of froth level, turbulence-free operation and no need for a blower or compressor comprise a user-friendly system

By Evren Ören, Lutz Markworth and John van der Heever

The Pneuflot pneumatic flotation system was introduced in 1987, with the first installation at Pittston Coal Co. in Pennsylvania for coal flotation. Since then, the technology has been widely used in coal flotation for treating fine coal slurries, and also for industrial minerals, ferrous minerals, nonferrous metals such as copper, lead, nickel and zinc, and for precious metals—platinum, gold and silver. The same size of equipment, with no changes in design, has been used in different applications all over the world, with the process eminently capable of handling material sizes of 80% passing 45, 180, 350, 500 or 1,000 ?m. Initial market conditions, with high…... read more
