2011-4-1 Chromite ore beneficiation practices The purpose of beneficiation is to render the ore concentrate physically (granulometry) and chemically suitable for subsequent treatments. Beneficiation practices depend on the mineral characteristics of the ore deposits, gangue mineral assemblage and the degree of dissemination of constituent minerals.

2012-10-12 Chromite ore beneficiation plants in Sukinda region treat selected rich ores (A-38% Cr203) with a view to producing concentrate of about 50% Cr203 as directly marketable grade for export and domestic industries. This has resulted rejection and piling of huge quantities of low and sub-grade ore (10-38% Cr203).
