Mining Media Hits Its Stride - The April 2007 E&MJ had a significant flop factor—a term publishers use to describe the sound the magazine makes when it hits the editor’s desk. This was due in large part to the bauma 2007 exposition that took place in Munich at the end of April. The print edition had more than 20 pages covering the show and E&MJ will publish post show coverage in a later edition.
Held every three years in the spring, bauma demonstrates Europe’s influence on the mining and construction industries. Even though many of the mines and mills in Europe have closed, the economies of several countries still depend heavily on the export of mining and mineral processing technologies ........ read more

A Closer Look at Reagent Consumption
Reagent performance is constantly improving, but is your plant keeping up as well? Tips on how to assess SX plant performance and reagent usage.
 
By Owen Tinkler, Cytec Industries Inc.

Reagent consumption is an important consideration in any commercial copper solvent extraction circuit. This article examines the main factors that influence reagent consumption and considers the validity of comparing the relative performance of different plants using the widely used “Reagent Usage” metric (described as the mass of reagent consumed in a given period of time, divided by copper cathode production for the same period of time). An alternative metric— called Net Reagent Entrainment, defined as reagent consumption during a given time period……. 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

Diesel developments
New compact engines share the spotlight with their big-bore brethren

By Russell A. Carter, Managing Editor

Think “mining diesel,” and generally what comes to mind is an eight-ton, 16- or 20-cylinder, twin-turbo’d beast bellowing under the strain of a 360-ton payload. But the reality is that there are many more medium- and small-sized diesel engines at work in mines, powering drills, utility vehicles, pumps, generators and other equipment. The large mining-class diesel engine segment—750 hp (560 kW) and up—has drawn a lot of attention in recent years as the industry’s demands for greater loading and haulage capacity escalated…. read more
