Heap bioleaching of chalcopyrite: A review
Quoted operating costs (2002), based on the current technology for leaching dumps and in-place ore, and is between US $ 0.18 and US $ 0.22 per pound of cathode copper, which are competitive with the unit costs of smelting/refining. Heap leaching has the additional cost of mining and transporting to the leach pad.

Chalcopyrite
Chalcopyrite is a copper iron sulfide (CuFeS 2) mineral with a brassy to golden yellow color (Fig. 1.36). Chalcopyrite contains 34.5% Cu, 30.5% Fe, and 35.0% S. The mineral is the principal source of copper metal, and one of the major source of sulfur. The mineral also contains traces of elements of gold and nickel and recovered in refinery.
