The Extraction of Copper Chemistry LibreTexts

Extracting of Copper from Other Ores. 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.

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. \(Cu^{2}S + O^{2} → 2Cu + SO^{2}\) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2

This process is known as SX-EW (solvent extraction/electrowinning).
