Ore Sorting vs. Dense Medium Separation 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.
