Copper is used in many different industries, including building construction, transportation, electronics and consumer goods. Minerals are concentrated in specific types of geologic formations (ore bodies), which are where mining takes place. These ore bodies may already contain naturallyoccurring radioactive materials (NORM).
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Copper industry practice for reporting operating costs is incompatible with the simplified cost models of Camm (1991). The Camm (1991) cost models estimate mining and milling costs separately and exclude byproduct credits and smelting, refining, and transportation costs. Mining costs are modeled in terms of dollars per ton of ore and
