01-04-2011  Rao et al. (1987), depicted that, low grade chrome ore with Cr 2 O 3 of about 20–30% of Sukinda region of India, can be beneficiated to a marketable grade of 45% Cr 2 O 3 with 45% recovery, by grinding the chrome ore (d 80 passing size 260 μm) and desliming the same using hydrocyclone and by treating the under flow on sand table and the overflow on slime table.

Chromite Beneficiation Process

In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate. In the concentration of certain chrome ores, high grade chrome particles are sometimes liberated at sizes larger than ¼”, For the concentration of these large size chrome particles, the Improved Harz Type Jig is indicated.
