Process mineralogical characterization of Kansanshi

2020-12-8  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

Mining Legislation and Mineral Development in Zambia

2020-10-13  Most copper production in Zambia occurs in an area known as the "Copperbelt."' Ten major mines are currently in production in the area,12 which is also the site of substantial prospecting and prep-aration operations. To a much lesser extent, Zambia produces other minerals.13 Cobalt, a by-product of copper production, is a growing export.

A case study in privatisation Mining For Zambia

A case study in privatisation. T he best time to measure the overall contribution of a mine to society is when it is about to close, and Chibuluma Mine on the Copperbelt is an ideal case-study. Chibuluma was one of the first Zambian mines privatised in 1997, and after more than 18 years of operation, it is nearing the end of its working life.
