A smelting technique is used to create ferrochrome alloys from chromite ores, and for every tonne of ferrochrome alloy produced, about 1.2 tonnes of FCS are typically created. The chemical makeup of the chromite ore, feedstock, amount of ash in the coke, and other reducing agents used typically determine this, though (Dube et al., 2018).

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. The quality of the product from the recovery process ...

Typical recovery figures are greater than 86% for alloy grades of 97% by mass. In addition to ferrochrome, the slag, which is largely a refractory spinel compound (i.e., MgAl 2 O 4), can be considered as a saleable byproduct. The leachate from the water leaching is evaporated to recover CaCl 2 which is then
