The determination of zinc by the back titration of excess potassium ferrocyanide is investigated and found very accurate and simple to perform. The use of the external indicator method is shown to be inaccurate and unreliable. A new indicator giving excellent results is developed for the titration of ferrocyanides with potassium permanganate. / Science, Faculty of / Chemistry, Department of / Graduate

Thesis (MTech. degree in Metallurgic Engineering)--Tshwane University of Technology, 2008. / The purpose of this study is to develop a feasible process for extracting gold and silver from an electrolytic zinc refinery residue. Composite samples of electrolytic zinc refining lead-silver residues containing traces of gold (1.35 g/t) and significant amounts of silver (155 g/t) were subjected to batchwise cyanide leaching to assess the feasibility of extracting gold and silver. This project was concluded with a recommendation that a pilot Residue Leach Plant should be commissioned to beneficiate gold and silver from the residue dam for a better estimation of lime, cyanide consumptions and gold and silver recoveries. The return on capital investment will be high at current gold price and operational cost is low. It is also recommended to investigate the economics of cyanide leaching of a pre-concentrate obtained from froth flotation.
