The Extraction of Copper - Chemistry LibreTexts

Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction.

Valves for copper leaching, solvent extraction and ...

The leaching, solvent extraction and electrowinning (LX-SX-EW) process is a widely used method in the production of copper from low-grade oxidized ore. Copper is the most common metal to be processed by LX-SX-EW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place is solvent extraction, which involves setting and ...

Liquid–liquid extraction - Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
