Mining Growth Accelerates in China and Miners Cheer - Working in the mining industry, or any industry for that matter, during high times can be exciting. Everyone has to work as hard—if not harder—than they do during lean times, but the positive nature of the business makes the additional workload seem a little more rewarding, especially for engineers who enjoy building new long-term projects. Naturally, when any group of mining professionals gather, the conversation inevitably turns to the question: How long will this bull market last? No one knows the answer, but right now China holds most of the cards.
Last month, the Shanghai Composite Index slipped for the second time this year and rattled markets worldwide. On April 19th, the index dipped 4.5%, which was not nearly as great as the 8.8% on Feb. 27th. The market reacted to an announcement from China’s statistic’s bureau saying ........ read more

Utility Gear Keeps Mine Wheels Turning
Without the myriad types of mobile, transportable, wheeled, tracked or skid-mounted utility gear found throughout mines worldwide....
By Russell A. Carter, Managing Editor

Primary loading and haulage equipment— the shovels, wheel loaders, LHDs and trucks that comprise the heavyweight segment of the mine fleet—generally get the most trade press attention due to their sheer size, power and fundamental importance in the production chain. However, utility equipment performs an equally important but less exciting role throughout the industry. Without the myriad types of mobile……. read more


Water Recovery with Ultraseps Technology

To whom do you turn for technology if you want to recover water from feed containing a high proportion of ultrafine material, specifically the tailings from spirals plants?

For two Brazilian iron ore producers the choice was Netherlands-headquartered Bateman Engineering. Both AVG Mineração, which is based in Belo Horizonte and produces lump ore and sinter feed, and V&M Mineração, whose Pau Branco mine is located in Brumadinho, Minas Gerais, use spirals plants that output tailings feed at rates between 90–95 mt/h. First, representatives of the two companies were shown Bateman-Ultrasep thickening technology in South Africa and visited operating installations. Following studies of process data and test work with client samples at Bateman Engineering’s Johannesburg laboratories, the solution offered to each of the Brazilian operators was the use of a 10-m-diameter Bateman-Ultrasep thickener, one of the larger sizes in a range covering 0.5- to 12-m diameter. Bateman says this...... read more

ToughMet Load Roller Bushings Extend Maintenance Cycles on a Large Electric Shovel

Extending maintenance cycles and maximizing productivity are consistent goals of mining equipment engineers and planners

By David Krus, Steve Geertson and Steve Metzger

Extending maintenance cycles and maximizing productivity are consistent goals of mining equipment engineers and planners. Every mine would like to have equipment components that never wear out. Component suppliers and equipment users alike understand that infinite life is impossible to achieve, but that does not stop users from challenging suppliers to find solutions that will last “forever.” Striving to find the holy grail, the part that virtually does not wear out, is one way for suppliers to win the business of maintenance-conscious mines. One such mine, near Seattle, Washington, USA, was attempting to maximize the efficiency of two P&H 4100XPB shovels. The mine valued productivity and took an “overall value” approach to maintenance..... read more



Software Modeling Cuts SAG Energy Consumption at Cortez Gold

Ore size reduction in mining operations is a significant contributor to energy consumption

By AbdulMajeed Aziz and Mike Mosser

Ore size reduction in mining operations is a significant contributor to energy consumption and mineral production costs. In fact, more than 50% of the total energy consumed in production of copper, gold and other mined commodities is spent on size reduction, and this energy intensity is exacerbated as plants process higher tonnage of ores of lower head grade. Semi-autogenous grinding (SAG) mills account for a large portion of the overall grinding energy input in mineral processing. Operation of existing SAG mills can be improved by conducting a plant sampling campaign using a flowsheet..... read more
