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.
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
