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.

How Gravity Separation Works to Recover Metals and Minerals
Gravity concentrators use the same principles of gravity separation at higher velocities. While conventional gravity separation happens at one G force, the Falcon SB uses up to 200Gs to concentrate microscopic particles as small as 20 microns. The same principles apply, just at a smaller scale. Dense particles will settle first, and light ones ...
