Bibliography: pages 96-100. The extraction of copper from chloride solutions with some aliphatic oximes as well as some pyridine carboxylates was studied and the complexes formed in the organic phase identified. The association of octanal oxime in toluene was taken into account in the extraction studies and formation constants for dimers and trimers obtained. Copper (II), Nickel (II) and Cobalt (II) are extracted by a solvating mechanism in which only the neutral MCl2 species is extractable. This reaction is largely independent of pH. Studies were also carried out on the use of the commercial reagent ACORGA CLX-20, for the selective extraction of copper from a synthetic solution simulating leach liquors obtained by ferric chloride leaching of complex sulphide ores. Results show that separation of copper from iron is dependent on the amount of acid and chloride present in the aqueous phase. 2016-01-15T14:19:13Z 2016-01-15T14:19:13Z 1986 Master Thesis Masters MSc http://hdl.handle.net/11427/16408 eng application/pdf Centre for Minerals Research Faculty of Engineering and the Built Environment University of Cape Town |
