dc.description.abstractKansanshi mine is the largest copper producer in Africa. The deposit is mineralogically and texturally complex due to supergene enrichment resulting in the presence of a variety of primary and secondary copper minerals. This necessitates the processing of ore through three separate circuits: sulphide flotation, mixed flotation and oxide leach, followed by solvent extraction and electro-winning. This study revisits the process mineralogy of the ore using modern mineralogy tools, which for such a large and complex deposit cannot but deliver significant value. Specific focus is given to copper mineralisation and the flotation of the sulphide ores in compliment to another MSc study from the Centre for Minerals Research focusing on mixed ore flotation (Kalichini, 2015). A series of hand samples and grab samples representing the variation in mineralogy and texture of the Kansanshi ore, as well as two run of mine sulphide ore flotation feed samples were used for this investigation. Process mineralogical characterisation entailed optical microscopy, XRF, QXRD, QEMSCAN and EPMA investigations, alongside a series of laboratory scale batch flotation tests of two sulphide ores at two grinds (80% passing 150 μm, 80% passing 212 μm). Copper mineralisation at Kansanshi occurs as both vein-hosted mineralisation, and to a lesser extent sediment-hosted mineralisation. Later breccia-hosted and supergene mineralisation have overprinted all previous mineralisation styles. Chalcopyrite is the main ore mineral for both vein-hosted and sediment-hosted mineralisation styles.en_ZA
