low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to size reduction, desliming and classification. The yield is low of about 25-35%. During beneficiation, sub grade intermediate products of about 35-40% Cr203 get generated which finds very little or no use and these have been accumulating in the mines.

Jul 18, 2013· The results gathered from shaking table test were not satisfactory due to low Cr 2 O 3 recoveries. However, a chromite concentrate with 46·22%Cr 2 O 3 grade and 66·1 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 ...

Apr 12, 2016· Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it …
