Extractive Metallurgy of Copper | ScienceDirect

About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores. Copper production from recycled end-of-use objects is .

Solvent Extraction in Hydrometallurgy - tms

Solvent extraction is a pivotal unit operation in many hydrometallurgical circuits, essential to facilitating flowsheet optimization and ensuring final product purity. Although it has been widely used in the copper and uranium industries for many decades, its use in other applications—especially those of high-tech metals, such as cobalt, nickel, scandium, and lithium—is less well known.

Solvent extraction definition and meaning | Collins ...

Solvent extraction is the separation of a particular substance from a mixture by dissolving that substance in a solvent that will dissolve it, but which will not dissolve any other substance in the mixture. The solution containing the desired metal is mixed with an appropriate solvent and the metal is extracted, in a process of solvent extraction.

The process involves leaching the material with a weak acid solution. This solution, known as pregnant liquor, is recovered and then contacted with an organic solvent, referred to as the extractant, in the solvent extraction stage (SX). Here the copper is extracted away from the aqueous phase leaving behind most of the impurities that were in the leach solution.
