ferrochrome crushing method

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