Iron ore beneficiation is therefore opposite to coal beneficiation where DMS is even more extensively used but where the floats represent the desired outcome. Another notable difference is that while coal DMS can use a cheaper medium made up of ground magnetite particles, the higher separation densities required in iron ore beneficiation (in the order of 3–4 kg/l) necessitate the use of ...

· Summing up, raw coal is usually crushed to 15 mm and then screened into three fractions 1525 mm, mm and – mm. The 1525 mm fraction is washed in heavy medium washer and the mm fraction either in jigs or heavy medium cyclones. The fraction is usually upgraded by flotation.

The cyclones used for beneficiation of fine coal are of two types – wateronly cyclones and heavymedium (HM) cyclones. The former type of cyclones is designed such that the cone angle is made relatively longer and no heavy medium is required for separation.
