The recovery of ferrochrome from slag at Zimasco

It is estimated that in Southern Africa alone there are some 60 million tons of Ferroalloy Slag containing entrained metal valued at about $1 billion. A highly efficient process has been developed to recover the valuable metals from slag in a form that is as far as possible directly salable. Six commercial plants have been built and are now operating, one of which is at Zimascoʹs ferro-chromium smelting complex in KweKwe, Zimbabwe. This plant is now producing saleable ferrochrome containing less than 2% slag at a recovery of over 96% of liberated metal
