Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallie. It is because of this fact that chromite is found in some concentrated ore bodies.
The only ore of chromium is the mineral chromite and 99 percent of the worlds chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
Chromite Ore Beneficiation Process or Chrome Ore Mining Process means Extraction of Chromium from Chromite Ore, and the gravity concentration solution has been proven that it is a cost effective solution for chromite ore process, there are many mineral separators which can be used for chromite ore beneficiation process, such as jig machine.
Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides e.g., PGE alloys, arsenides, bismuthinides. The oxide ore bodies include stratiform, podiform, and breccia-related chromite.
