Chromite Ore Crushing. The crushing section for this 250 ton per day chrome mill consists of a coarse ore grizzly, a coarse ore bin with pan feeder to a 1’8″ reduction crusher and a crusher discharge conveyor to a crushed ore bin. On this particular ore, we find that there is no chrome liberated in sizes larger than ¼”.

ores. Thermal beneficiation was successfully carried out on a low grade chrome ore from Vagda deposits, Ralnagiri District, Maharashtra India. The method employed was preferential roasting reduction and acid – leaching. The initial chromium – iron ratio of 1.53:1 was increased by this approach to 8:1 with more than 87% chromium recovery.

Chrome ores contain a variety of gangue minerals such as goethite, gibbsite, serpentines, olivine etc., which needs specific concentration techniques for separation and thus beneficiation of the ore. During mining operations, large quantities of sub-grade ores ranging 10-35% Cr2O3 are also excavated.

Inference on Beneficiation Results of Low-Grade chromite Ore. The beneficiation studies of low-grade chromite ore from Ghutrigaon reveals that it can be upgraded through physical beneficiation methods. Following gravity concentration technique, a feed of 16% Cr 2 O 3 can be upgraded to 40.1%, with 23% yield, 58% recovery and Cr/Fe ratio of 3.35.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity. Many

Beneficiation. Run of mine ore is crushed to size when it reaches the surface. A certain percentage may be milled further. The ore is then sorted to different size fractions by means of a dense media separation process. Silica is removed from the finer fractions by means of gravity and elutriation separation techniques.
