PDF Recovery of chromium from ferrochrome slag
Ferro chrome slag may contain chromium in 3 and 6 oxidation states. Separation and determination of chromium content of the slag samples collected from Jindal Ferro Alloys Corporation Kottha
CHROMIC: NEW PROCESSES TO RECOVER METALS FROM CARBON STEEL
For the carbon steel slag originating from an EAF three particle sizes were studied 05 mm 2040 mm 40185 mm . The ferrochrome slag was crushed and sieved to a 49 mm fraction. The stainless steel slag is a finegrained fraction lt 500 m obtained after a crushing screening and demetallisation treatment. For the characterization
Recovery of Chromium from Ferrochrome Slag Open Access Journals
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.

PRODUCTION CHARACTERISTICS AND USE OF FERROCHROMIUM SLAGS
the right slag composition. The slag composition is tested every day by sampling and analysis. The typical ferrochrome slag composition is 30 SiO 2 26 Al 2O3 23 MgO and 2 CaO. The chrome content in the slag is about 8 and the iron content 4 respectively. Ferrochrome slag is acid. Its basicity is 0.8 when it is calculated by
The recovery of ferrochrome from slag at Zimasco ScienceDirect
Recovery of ferrochrome from slag 1255 While being attractive financially the process also allows metal free tailings to be disposed of in a more environmentally friendly manner. Where required a window of opportunity is also provided for the removal and disposal of potential pollutants from slag dump sites.
Recovery of alloy from Ferrochrome SlagFerrochrome recovery
Ferrochrome smelting slag processing line is mainly to recover the valuable ferrochrome alloys from the slag in a forms that will be as far as possible directly saleable. This production line is now producing saleable ferrochrome containing less than 2 slag at a recovery of over 96 of liberated metal.
