May 04, 2020 A new solvometallurgical process. In this new SIM KU Leuven study, a solvometallurgical process for the extraction of copper from sulphidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidising agent and ethylene glycol (EG) as organic solvent) (see Figure 1 ).

May 04, 2020 May 4, 2020. SIM KU Leuven researchers have developed a new solvometallurgical extraction process to produce copper from sulphidic copper ore minerals such as chalcopyrite (see featured image). The innovation comprises a closed-loop process, using Ethylene glycol-FeCl3 as lixiviant. Metallic copper can be obtained by direct electrodeposition from the pregnant solution and, in

Jun 07, 2021 The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate
