  • Extraction Of Copper | Mining, Concentration, Smelting

    The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides The percentage of copper in the actual ore is too low for direct extraction of copper to be viable The concentration of ore is required and it is done by the Froth Flotation method Concentration of Ore: The ore is crushed into a fine powder and a suspension isExtracting copper from other ores Copper 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 extraction The very dilutecopper extraction and purification chemguide· Since it is common for the copper solvent extraction plant to supply feed electrolyte to an electrowinning plant, it is useful to combine the operating costs for the two plants when comparing costs of copper recovery by solvent extraction techniques with those for cementation These have been summarized in the table which shows typical operating costs for a plant producing 30,000 annual tonsCopper Recovery by Solvent Extraction Techniques

  • Extraction of Copper from Copper pyrite | Grade 12 Science

    The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized The ore being sulphide ore is concentrated by froth floatation process Pulverized ore is kept in water containing pine oil and the mixture is agitated by passing compressed air Ore forms froth with pine oil and comes toConventional Copper Extraction Conventionally, copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined, crushed, ground, concentrated, smelted and refined The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate theHow Hydrometallurgy and the SX/EW Process Made Copper the· For instance, in copper extraction, the loaded organic solution is stripped with a high strength sulphuric acid solution to produce a strong solution of copper sulphate suitable for electrolysis In several cases the production of a pure aqueous solution of a metal salt is the final objective and the solution is reused in processes such as plating or the salt is recovered by crystallisationSX Solvent Extraction of Metals: A Design Manual
