PRODUCTION, CHARACTERISTICS AND USE OF
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

The Benefits of Using Gravity
The leading suppliers offer their outlook on the current state of gravity-separation technology. By Simon Walker, European Editor. With the possible exception of visual sorting—"this one's green, this one's not," or however the Bronze Age equivalent ran—being able to separate minerals using differences in their density is the most ancient mineral-processing technique known to man.

The stability of ferrosilicon dense medium suspensions
Dense medium separation is the process in which a heavy liquid of an intermediate density is used to separate minerals of different specific gravity. The heavy liquid is typically a suspension of dense powder such as ferrosilicon or magnetite in water. Ferrosilicon is used for high-density applications (medium density: 3200–4200 kg/m3).
