The Geological Occurrence, Mineralogy, and
Chromite is naturally hydrophilic and probably reports to the concentrate by entrainment. It is possible to reduce chromite in the concentrate by the use of gravity separation prior to secondary grinding or by reducing entrainment through reduced water recovery. However, it is worth noting that recently, chrome has become an economically important by-product.
