Copper Mining and Extraction: Oxide Ores
The flowchart above shows how the smelting process of sulfide ores produces sulphur dioxide, which is converted to sulfuric acid. The chart below shows how acid is used to leach out copper ions creating lakes of blue copper sulfate solution from which copper is recovered in a solvent and then electrolytically refined in a process called solvent extraction and electrowinning (SX-EW).read more

Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron ...read more
