FEATURE - Trolley Assist
The Case for Trolley Assist
High fuel prices are the main reason mine operators consider trolley assist for haul trucks, but safety and sustainability are also important considerations

By Dr. Joy Mazumdar

Advances in electric-drive haul truck technology over the past 20 years have been remarkable. The drive systems for these trucks consist of two electric drivemotors that are integrated through gears into the rear wheels of the trucks, an electric generator and a powerful diesel engine. The characteristics of the truck’s drive system allow it to harness electrical power directly. In some parts of the world, electrical power can be generated inexpensively and with less emissions, depending on the fuel source. Truck trolley systems, which simply substitute electricity for diesel fuel, may offer another……. read more

Paste Thickening: Considerations for Backfill vs. Tailings Management
Finer grinds improve liberation rates but increase the costs associated with tailings disposal

By Frank Palkovits, P. Eng.

Profitability is directly related to recovery, and generally improved with increasing grind. However, economic limits should also include consideration of tailings management and backfill costs. Depending on the type of tailings storage facility (TSF), the particle size distribution (PSD) can greatly influence the cost of dams and need for borrow materials, as well as the geotechnical properties and geochemical behavior of the system. For mines requiring backfill, rheology and strength are also a function of PSD.The coarse sand fractions of tailings have often been used in conventional tailings embankments, and also used in hydraulic backfill. In both cases the slimes are removed to provide a highly permeable product for strength required. The fines in this arrangement are typically stored in a central pond on top of the tailings impoundment. The need for the sand.... read more

Iron Ore Review
High Prices and Tight Markets to Continue Until 2013?

By Magnus Ericsson, Anton Löf and Olle Östensson

The world iron ore market in 2010 was dominated by a resurgence after the stimuli packages, put in place in 2009 following the global financial crisis, took effect. However, the industry experienced rough times in 2009 and the resulting changes following the economic slump produced effects that probably will live on as permanent features. Trading patterns have been transformed, and Chinese dominance has become even more massive. Steel Production: Up Globally, Growth Slower in China. World crude steel production increased to 1.396 billion mt in 2010 from 1.201 billion mt in 2009, a change of 6.2%, driven by the recovery of the world economy and rising industrial production, mainly in emerging countries but also in the OECD area. Production was well above …... read more
