    8.1.7.4 Chromium from Chrome Slag. 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.
