Jun 13, 2019 Generally speaking, chromium ore contains a certain amount of iron, so gravity separation - magnetic separation process is the common chrome ore beneficiation process. Of course, the ore beneficiation process hall be determined according to the indicators obtained after the mineral processing test. 1.
Chromium is largely used as alloying elements in steels for production of stainless steels. It is added in form of ferro-chromium, which is presently imported from Russia and Germany to meet the need of Nigerian Steel Industry. Chromite ore FeOCr2O3 is the most important mineral occurrence of chromium, and some deposits are reported in Anka Local Government Area of Zamfara State.
Chromium processing, preparation of the ore for use in various products. Chromium Cr is a brilliant, hard, refractory metal that melts at 1,857 C 3,375 F and boils at 2,672 C 4,842 F. In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
