CHROMIC: NEW PROCESSES TO RECOVER METALS FROM

For the carbon steel slag, originating from an EAF, three particle sizes were studied (0-5 mm, 20-40 mm, 40-185 mm). The ferrochrome slag was crushed and sieved to a 4-9 mm fraction. The stainless steel slag is a finegrained fraction (< 500 µm) obtained after a crushing, screening and demetallisation treatment. For the characterization

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 can be regenerated to recover chromium. REFERENCES 1.
