COBALT RECOVERY FROM SOUTHERN AFRICAN COPPER SMELTERS
Cobalt occurs together with copper in the southern African copper belt, and a large portion of this cobalt ends up in copper smelting slags, mostly dissolved in oxide form. We report chemical, petrographic and metallographic studies of copper ores and slags recovered during sporadic surface surveys and excavations over the past Copper mining and smelting technology in the northern

An Overview of Copper Smelting in Southern Africa
Africa’s share of global mined copper production was about 10% in 2014; however this will increase significantly in future if announced new projects eventuate. Southern Africa has an important role to play in this process. The present paper provides a brief overview of copper smelting in Southern Africa. Ancient History of Copper SmeltingWe report chemical, petrographic and metallographic studies of copper ores and slags recovered during sporadic surface surveys and excavations over the past fifty years in the Phalaborwa and Murchison Range areas of the northern Lowveld of South Africa. The copper slags around Phalaborwa have unusual mineral assemblages, Copper mining and smelting technology in the northern Lowveld, South

The technology of tin smelting in the Rooiberg Valley, Limpopo Province
A substantial indigenous tin-smelting industry arose in the Rooiberg valley of northern South Africa in the second millennium CE. This study concentrates upon tin-smelting slags and refractory ceramics from two archaeological sites that date between ca. 1650 CE and ca. 1850 CE. These were studied by optical and electron microscopy, In May 2008, Platmin announced it had accepted South African power utility Eskom’s quotation for 37MVA of new power supply for Pilanesberg. The installation will consist of a new Pilanesberg regional Platmin Platinum Mine, Pilanesberg Mining
