THE RECOVERY OF FERROCHROME FROM SLAG AT ZIMASCO

It is estimated that in Southern Africa alone there are some 60 millio n tons of Ferroalloy Slag containing entrained metal valued at about $ 1 billion. A highly efficient process has been developed to recover th e valuable metals from slag in a form that is as far as possible direc tly salable. Six commercial plants have been built and are now operati ng, one of which is at Zimasco's ferro-chromium smelting complex in Kw eKwe, Zimbabwe. This plant is now producing saleable ferrochrome conta ining less than 2% slag at a recovery of over 96% of liberated metal. (C) 1997 Published by Elsevier Science Ltd.
