  • Chrome Ore Beneficiation Process Chromite Processing

    The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite. Besides, the grain size is fine, so there is no need for grinding, the grading result shown in the below.

    Keywords: Low Grade Chromite Ore, MGS, Beneficiation. 1. Introduction Chromite is recognized as an essential mineral for the production of various types of stainless steels and special ferrochrome alloys. In addition to its application for various purposes in refractory, chemical and ceramic industries etc. It is a valuable and prime source of chromium element. Chromite ores occur exclusively

  • Beneficiation of Low Grade Chromite Ores from Sukinda

    of the chromite ore beneficiation plants in Sukinda region treat selected rich ores with rejection of huge quantities of low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to crushing, grinding, desliming and hydrosizing to produce a concentrate of about 50% Cr203 with a yield of about 25-35%. By this also, a huge amount of sub grade fines of about 35-40% Cr203 has been
