JXSC jig concentration machine is energy-saving gravity separation equipment, which is developed according to the law of layer theory of jigger bed stratification. The performance of saw-tooth Jig has reached the domestic advanced level, the jig separator is one of the ideal devices in energy-saving gravity separation. 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.
