The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
8.2: Mining and Ore Processing
Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2). When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a …
BHP Ravensthorpe Nickel Operation, Australia
Ravensthorpe was a laterite nickel project which, because of the ores' low grade, and expensive and intensive processing requirements, has caused BHP some headaches. The project was originally approved in March 2004 with a budget of $1,340m. But by November 2006, capital costs rose to $2.2bn. The company did not officially open …
