Chromite Beneficiation Process

19/03/2017  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

Chrome Ore Beneficiation Process Chromite Processing

The results of this study show that, after the first rough separation, the grade of chromite concentrate Cr2O3 is 32.06%(13% higher than the grade of raw ore), the productivity of that is 48.88%, and the recovery rate of that is 83.04%. In order to know the Cr2O3 distribution among the concentration and tailings, make a grade sieving in the roughing concentration and tailings respectively.

23/03/2016  The applicability of centrifugal force multigravity separator (MGS) to concentrate fine fractions (–01 mm) of a low grade chromite ore assaying 93%Cr 2 O 3 was investigated. The metal screen analysis revealed that 8392% of the material prepared for tests was in the +0106 mm fraction containing 8%Cr 2 O 3 and that 1608% was in the –0106 mm size fraction containing 1612%Cr 2 O 3 .
