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.

Tester Group - Research

Successful supercritical fluid extraction (SFE) of metals was first accomplished with copper in the 1990s. A supercritical fluid is a substance at conditions above the critical point. The characteristics of supercritical fluids are a mixture of liquid and gas characteristics that can be tuned by small alterations in pressure and temperature.
