Chrome ore beneficiation challenges & opportunities A

Apr 01, 2011 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.
