The hydrated metal-ion is stripped of the water molecules and form complexes with the active component in the organic phase. Thus, the metal-ion is transferred from the aqueous phase to the organic phase. The metal ion can then be stripped from its complex (in the organic phase) using an inorganic acid or aqueous salts …

Extracting copper from its ores. 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 …

Hydrometallurgical processes are suitable for the extraction of metals from low-grade ores and secondary raw materials (Jiang, 2017, Spooren et al., 2020), and the most common mineral types that can be treated with hydrometallurgical processes are silicates, sulphides and oxides (Burkin, 2001). Hydrometallurgical processes tend to be …
