MINERAL PROCESSING Grinding and concentration together consume about 45 percent of the energy used in the pro-duction of cathode copper. Assuming an ore grade of 0.55 percent and a recovery rate of87.5 6.4 percent copper in the concentrate, concentrat-ing 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of

Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

The mills were selected on the basis of two milling trains, each comprising the largest SAG and ball mills currently proven at other operations, at the time of design. On that basis, a 28 MW SAG mill (internal diameter of 12.19 m (40 ft)) and a 22 MW ball mill (8.53 m internal diameter (28 ft)) were selected for each milling train.

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill
