a successful jigging process has been developed to recover ferrochromium metal from waste dumps. the potential for generating cr(vi) during this operation has been investigated.,recovery of chromium from ferrochrome slag,recovery of chromium from ferrochrome slag is 64 by treatment of slag with lime at 973k in solid phase. the soluble chromium ion was extracted with water. the chromium from liquid extract is separated with fly ash based zeolite which has 3000 mmol/gram and it
