The process of chromite ore mining can be divided into 2 areas: 1. Feed preparation. 2. Concentration. The feed preparation stage involves the introduction of various physical separation equipment including crushers, screens and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase. The concentration phase introduces hydrocyclone ...

Chromite: The only mineral ore of chromium metal

Stratiform, Podiform, and Beach Sands. Small amounts of chromite are found in many types of rock. However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the ...

Chromite - ScienceDirect

01/01/2016  Residues from mining and chromite processing are often toxic, not only because of the presence of hexavalent Cr (Cr(VI)) but because of the reagents and other waste materials in overburden and wastes. Governments have undertaken to update some Cr regulations, many of which have resulted in stricter standards. Current efforts are being made to reduce waste or eliminate its hazardous
