Dense Medium Separation Iron Ore

The art and science of dense medium selection

Iron ore - in the form of haematite, pure iron ore has a particle density of 5.2 t/m3 and it is separated from siliceous material with a particle density of 2.65 t/m3. The mixture of ore and medium is introduced into separating vessels within which the separation take place.
