Ore Sorting Strategies In Mineral Processing

Ore sorting can run into capacity and efficiency issues if particles are below 30mm. In contrast, dense medium separators can sort particles down to 0.75mm in size. If you're working with finer particles, dense medium separation is the way to go. Higher tonnages can also be accommodated with dense medium separation.

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).
