v116n6a1 Copper mining in Zambia history and

copper sulphide minerals from ores had been commercialized and this advance enabled large quantities of copper to be produced. The mine owners therefore invested in concen-trators, smelters, and other metal extraction facilities, a situation which continued until 1969. By 1964, Zambia was a major player in the world copper

Mining Legislation and Mineral Development in

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. Large

Process mineralogical characterization of Kansanshi

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.
