beneficiation of low grade chromite

Beneficiation of low grade chromite for preparation of

up-grading the so far rejected chromite ores. Keeping this in view, in the present investigation, some very low grade chromite samples were taken for laboratory scale beneficiation. Characteristics of the chromite samples Four chromite samples from rejected dumps and overburden materials of a chromite mine, were collected for their beneficiation.

An efficient process for the beneficiation of a low grade

Mar 23, 2016  The results gathered from shaking table test were not satisfactory due to low Cr 2 O 3 recoveries. However, a chromite concentrate with 4622%Cr 2 O 3 grade and 661 wt-%Cr 2 O 3 recovery was obtained by the combination of shaking table and MGS. It was clearly demonstrated that MGS is an ideal beneficiation equipment for fine fractions of a

Kinetic Studies on the Reduction of Iron Oxides in Low

In a novel method of beneficiation of low-grade chromite ore, nuggets, 25 mm in diameter and 10 mm long, made of chromite ore and coke fines, are subjected to partial reduction. A significant degree of reduction of iron oxide is observed at temperatures of 1373–1523 K up to a reduction time of 240 min, and subsequent magnetic separation is found to enrich the low-grade chromite ore.
