What China is Doing to Africa: Copper Beneficiation in …
Botswana's copper and base metals firms are in discussions along with the government over the road ahead for beneficiation in the country. Two things are pretty clear: the copper companies want nothing to do with the country's desire to beneficiate its base metals; and the iron ore and coalminers do, at least for the moment.
