copper mining and processing cost structure

Part Four Competitiveness Princeton University

The costs of mining and processing copper are more closely related to the gross tonnage of the ore than the net tonnage of copper in the ore.5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore con-tains more copper, it requires less of these inputs

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing
