Recovery of alloy from Ferrochrome Slag,Ferrochrome
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.

Recovery of Chromium from Ferrochrome Slag JOCPR
chromium content of the slag samples collected from Jindal Ferro Alloys Corporation, (Kottha valasa, Visakhapatnam Dt.) has been carried out following extraction with benzene solutions of TOAO(0.01M). Maximum extraction efficiency was achieved at pH 2.5M in presence and absence of impurities associated with ferrochrome slag.

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

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

Effect of Chrome Ore Quality on Ferrochrome Production
Chromium recovery mainly depends on reducibility of the ore. From the input Cr to the furnace, other than recovered Cr to metal, the balance mainly reports to slag and some to furnace dust. With reference to hard and dense ore, the dust portion is low, but depending on ore reducibility and its size, the Cr2O3 content of slag could increase.

Production of Ferro-Chrome IspatGuru
Jul 10, 2018Slag temperatures of upto 1650 deg C always result to C content of 7 % to 8 % in the Fe-Cr. Only if the MgO content of the ore is high and the slag temperatures exceed 1700 deg C then the C content is in the range of 4 % to 6 %. Lower C levels cannot be reached in the SAF and a second process step is needed. Raw materials

Ferrochrome an overview ScienceDirect Topics
The most common recovery process is to crush the slag (in the case of the first slag-handling method) and recover the alloy particles in a wet jigging process. In particular cases where the high carbon ferrochrome is sufficiently magnetic, magnetic separation techniques can also be applied.

Production of Ferro-Chrome IspatGuru
Jul 10, 2018The fine chromite ore is very readily reduced in solid state before it is melted, resulting in a Cr2O3 content in the slag in the range of 1.5 % to 4 %. Also it is important that there is complete separation of liquid ferro-alloy and slag during tapping so that the liquid Fe-Cr going to slag is minimal for the optimization of Cr recovery.

The alloy content in the slag is substantial and comprises typically 1% to 4% of the total alloy tapped. It is therefore normally viable to attempt recovery of this alloy from the slag. The most common recovery process is to crush the slag (in the case of the first slag-handling method) and recover the alloy particles in a wet jigging process.
