v116n6a1 Copper mining in Zambia history and future
copper sulphide minerals from ores had been commercialized and this advance enabled large quantities of copper to be produced. The mine owners therefore invested in concen-trators, smelters, and other metal extraction facilities, a situation which continued until 1969. By 1964, Zambia was a major player in the world copper
Copper Mining and Extraction Oxide Ores
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores 1114, but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Copper processing Ores Britannica
Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

The SX process consists of extracting Cu 2 from aqueous PLS into a copper specific organic extractant, separating the aqueous and organic phases by gravity, and then stripping Cu 2 from the organic extractant into high-H 2 SO 4 electrolyte returned from the EW circuit. The process is continuous and is carried out in large Mixer-settlers.
