Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Technique of Magnetic Separation. Each mineral is separated based on its magnetic susceptibility. Ferromagnetic minerals - The poles of a magnet are wrapped in paper and passed over the mineral mixture. Ferromagnetic minerals will stick to the magnets and, thus, get separated from the ore mixture. Paramagnetic minerals – These are weakly ...
