Abstract:
On sample of smelting slag, containing 0,71% of copper (76,71% sulphide copper and 23,29% oxide copper), it was investigated possibility of agitation leaching with sulphuric acid with and without of oxidants presence. Since the content of oxide copper is relatively small in the relation to content of sulphidic copper, process of agitation leaching is provided in presence of following oxidants, iron (III) sulphate Fe2 (SO4) • H2O and iron (III) chloride FeCl3 • 6H2O. It was also tested the influence of the oxidants concentration on the leaching degree of total copper. By using iron (III) sulphate leaching degree of total copper has increased from 23,3% to 30,5%, while the application of iron (III) chloride FeCl3 • 6H2O increased level of total copper leaching to 44,7%.
