chromite heavy media separation

Heavy Media Separation - an overview ScienceDirect

A typical technological process of chromite ores enrichment includes a series of operations (Lyakishev and Gasik, 1998): screening of the input ore, slurry rinsing-off, and heavy media separation. The slurries formed are subjected to wet screening, dehydration, filtration, and drying.

Heavy media separation with dense Magnetite LKAB

Heavy media gravity separation means separating products with different densities. Both magnetite and water are used to make a slurry on which one product will float (the product with a lower density than the slurry) and in which the other product will sink (the product with a higher density than the slurry). Hence our customers often use the term sink-and-float separation.
