Chromite (FeCr 2 O 4) is a mineral belonging to the spinel group of minerals characterized by the following formula [(Mg,Fe 2+)(Al,Cr,Fe 3+) 2 O 4] (Haggerty, 1991). The largest exploitable deposits of chromite occur in South Africa and Zimbabwe, with significant deposits in several other countries such as Finland, Kazakhstan and Turkey.

Setting up a Chromite Beneficiation Plant will enrich the Chromite content of the ores, liberate them from unwanted rock material and other minerals and eventually separate the final product into uniform grain sizes. In other words, the purpose of beneficiation is to render the ore physically and chemically suitable for further treatment.
