Extractive Metallurgy of Copper | ScienceDirect
Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for some operations when the selling price falls below $3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid-2011 was ∼$9/kg.

Innovations: Introduction to Copper: Mining & Extraction
Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest ...

SX EW Capital & Operating Cost of Solvent Extraction & Electrowinning
As a result each mixer settler is ½ the size of those in the 2×1 circuit and the total settler area is only 66.7% of that of the 2×1 circuit. The cost saving is estimated to be about 29% which gives a capital cost of $5.0 million. The electrowinning capital cost is the same for each plant and is based on a copper production of 27.2 tonnes/day.
