The Extraction of Copper Chemistry LibreTexts
Extracting of Copper from Other Ores. Copper can be extracted from nonsulfide 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.

design and optimization of copper solvent extraction
This value gives copper extraction efficiency greater than 98% and copper stripping efficiency of 60%. Afterwards, understanding that copper extraction efficiency was not the most important parameter than the cost of copper production plant, one stage of stripping step was removed and the value of copper transfer was increased to 0.26 (g/l/1%V).

Extractive Metallurgy of Copper ScienceDirect
Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world''s copperfromore 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.

Mechanism of crud formation in copper solvent extraction
The authors investigated the mechanism of crud formation in copper solvent extraction. It is indied that pH value of solution and the phase ratio (O/A) are the main factors affecting crud formation in solvent extraction. The amount of crud extraction increases with aqueous pH value increase, and reduces with the increase of the phase ratio.
