magnetic separation of ferrochrome
Wet gravity separation by Reichert cones plus slimes treatment was added in 1979. Heavy media separation (HMS) replaced screening for the recovery of lumpy concentrate in 1984 and the Sala high-gradient magnetic separation (HGMS) system was adopted for treating slimes in 1995.

The density of the ferrochrome slag is between 2.5- 2.8 g/cm 3 and that of ferrochrome 6.8 g/cm 3. The viscos-ity of slag is a function of the pressure and temperature. The viscosity also has an essential meaning in the separation of slag and metal. The viscosity of the fe rrochrome slag will increase when the content of SiO 2 and
