AB The method of processing copper raw material into copper oxide is suggested and investigated This method is based on the decomposition of copper oxide and sulfide by ammonium chloride with the subsequent leaching of chloride compounds of copper and the precipitation of copper hydroxide from the solution
Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta Chile was investigated after leaching with a chlorideferrous media at two temperatures
copper extraction 5023 was achieved at 329 C with the addition of 06 kg of H 2SO4 per ton of ore 0525 kg of NaCl per ton of ore and 05 kg of FeSO4 per ton of ore In respect to copper
Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta Chile was investigated after leaching with a chlorideferrous media at two temperatures The study focused on whether this chemical leaching system could be applied at an industrial scale Leaching tests were conducted in columns loaded with approximately 50 kg of agglomerated ore the
Mar 01 2017 · Primary copper sulfides are the most economically relevant due to their abundance Therefore several technologies have been developed in order to achieve an efficient copper extraction from these types of copper sulfides Among these developments the hydrometallurgical options of bioleaching as well as chemical chloride leaching are
The Cuprex metal extraction process produces cathodegrade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrates The process incorporates several novel steps to overcome the major problems associated with earlier chloridebased processes including mild leaching conditions using ferric chloride as leachant and solvent extraction of copper usinga
VMS oreforming fluids are acidic reduced 1–3 M chloride solutions in which metals were transported mainly as chloride complexes Table 3Before the discovery of black smokers temperatures of the ore fluids were estimated from rare fluid inclusion data and sulfur isotope fractionation between sulfide mineral pairs pH values about 1 unit less than neutral 5 at 250 °C were determined
Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate carbonate or sulphate ores Getting copper from chalcopyrite CuFeS 2 Chalcopyrite also known as copper pyrites and similar sulphide
