Includes bibliographical references. This study is a preliminary investigation into the mechanism and kinetics of Rh3+ coprecipitation with CuS upon aqueous thiosulphate addition to acidic base metal sulphate solutions, where Rh3+ concentration is two orders of magnitude lower than Cu2+, over 50 - 150 °C. The heterogeneous cationic substitution has been identified as a new precipitation path in metal sulfide co-precipitation, namely, the reaction between more soluble, co-precipitated metal sulphide (CuS) and the less soluble cation in solution (Rh3+), with the large KSP difference providing the chemical driving force. 2014-07-31T11:16:39Z 2014-07-31T11:16:39Z 2007 Master Thesis Masters MSc http://hdl.handle.net/11427/5442 eng application/pdf Department of Chemical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
