Indaba Debates the Future of African Mining

During April 2013, the mining business suffered some setbacks. As can be seen on the cover of this month’s edition, the miners at Kennecott Utah Copper’s Bingham Canyon mine now face an uncertain future. Prices for most metals declined during the month, but it was the falling price of gold that garnered the most attention. Many new mining CEOs were preparing first quarter earnings reports, announcing their plans for the future, deciding what paths to pursue, and which projects to table. Scaling back ambitious plans is never easy for mining engineers. Sometimes the market or natural forces make the decision for them.

Bingham Canyon symbolizes the advances the open-pit copper mining and processing industry has made over the last century. Starting with Daniel C. Jackling, who was a visionary as far as the approach to mining and processing a massive low-grade porphyry deposit, the engineers that earned their stripes at the mine and the Copperton mill revolutionized the copper industry. That’s why it should come as no surprise that the engineers knew it was going to happen and they were able to prepare for itt......... read more

Huge Landslide Halts Ore Production at Rio Tinto’s Bingham Canyon Mine
Operations at Rio Tinto’s flagship copper mine, the Kennecott Utah Copper Bingham Canyon complex near Salt Lake City, Utah, USA, have been severely curtailed by a massive pit-wall failure that occurred April 10. Latest estimates from the company indicate the slide, which took place in the northeast corner of the pit, involved at least 150 million tons of material and filled the bottom of the pit to a depth of 300 ft (91 m) in some areas. The landslide was described by KUC’s president and CEO, Kelly Sanders, as one of the largest in mining history........ read more

Careful Monitoring: The Key to Pit-wall Safety
As mines get deeper, and economic pressures provide an incentive for steeper pit walls, the potential for instability increases. E&MJ looks at some of the systems that can help mine engineers keep an eye out for signs that all may not be well within the wall.

By Simon Walker, European Editor

On Friday, April 11, Rio Tinto issued a press release that read: "At 9:30 p.m. local time on April 10, 2013, Kennecott Utah Copper’s Bingham Canyon mine experienced a slide along a geotechnical fault line of its northeastern wall. Movement on the northeastern wall had accelerated in recent weeks and preemptive measures were taken to relocate facilities and roads prior to the slide. All employees are safe and accounted for." Speaking a few days later when presenting the company’s first-quarter operational review, CEO Sam Walsh expanded a little on the effect that this may have on Rio Tinto’s copper production for the rest of this year. "At Bingham Canyon, last week’s pit-wall slide will have a significant impact on our copper production this year," he said. "A recovery plan is being implemented to minimize the economic impact……. read more

Mining must become more adept at finding acceptable water-source solutions in an increasingly complex, thirsty world

By Russell A. Carter, Managing Editor

Water and gasoline generally don’t get along well together, but these two commodities have more in common than many people realize. When used in large volume, both must be managed carefully to control costs and ensure adequate supply. In the future, demand for both is expected to grow dramatically, driven by expanding population levels and lifestyle expectations from new middle-class consumers in rapidly developing countries. Consequently, both are also expected to become more expensive, inflated by heightened demand and limited supply. And, both have incendiary properties that can be useful or destructive: Gasoline is volatile, yet necessary to power much of the world’s vehicular motion; while water—or more often, lack of it—has the ability to inflame civil unrest that can halt an industrial or mining project in its tracks…... read more

Comparing the Cost of Dust Collector Bags vs. Cartridge Filters for Mining Applications
There are two primary types of dry dust collection systems used to control dust at mine sites, mill transfer points and similar locations: baghouse collectors that use rows of large filter bags and cartridgestyle collectors that use much smaller pleated filter elements. Though baghouses have been the traditional choice, cartridge collectors have gained popularity over the past decade because they offer several advantages over baghouses. A cartridge collector has a much smaller footprint than a conventional (i.e., nonpleated) baghouse and operates at lower pressure drop. It can also achieve significantly higher filtration efficiencies— a potentially important advantage since, if emissions are too high, regulators may curtail production…. read more
