EXTRACTION OF COPPER University of Technology, Iraq
EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting Ores containing 4% or more copper are treated by smelting process Very poor ores are treated by hydrometallurgical process EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copperCopper can be extracted from nonsulphide 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 sulphuric acid to produce a very dilute copper(II) sulphate solution Concentration of the copper(II) sulphate solution by solvent extractioncopper extraction and purification chemguide
Copper Mining & Extraction Process Flow Chart
26082015· This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper This process as the advantage of avoiding the smelting and refining stages required for sulfide ores Thanks to http://wwwflsmidth/Cu + O 2 + CO 2 + H 2 O → CuCO 3 Cu (OH) 2 Moist air basic copper carbonate On heating in air 900 0 c, copper forms cupric oxide or black oxide of copper, 4Cu + O 2 900 → 2CuO Cupric oxide On further heating above 1100 0 c, copper gives cuprous oxide or red oxide of copper 4Cu + O 2 1000 → 2Cu 2 O Cuprous oxide Action of water:Extraction of Copper from Copper pyrite | Grade 12 Science
