Handling of Smelter Feed-A Purpose-Oriented Approach

As the heart of a copper-producing complex, a smelter converts raw copper concentrates or leach-plant precipitates, or both, into blister copper. A typical smelter feed also contains matte chips, flue dust, flux, and lime. All these materials vary widely in their characteristics, ranging from sub-micron to lumps, from slurry to dust, from abrasive to corrosive, and free-flowing to adhesive. Handling all these materials becomes even more problematic since most of the world's open-pit copper mines are located in a semi-arid zone where rainfall is minimal.
