Apr 01, 2011  Beneficiation practices depend on the mineral characteristics of the ore deposits, gangue mineral assemblage and the degree of dissemination of constituent minerals. In general chromite beneficiation flow sheet ( Fig. 2 ) has two major sections: comminution (for preparing the material to the subsequent unit operations) and concentration.

Chromite: from the mineral to the commodity

The most commonly used beneficiation methods for chromite ores are the gravity methods, such as the shaking table, jig, spiral and Reichert cone methods. The present work deals with the geologic studies that, coming after prospection, lead to the evaluation of the chromite ore quality and to planning and/or improvement of beneficiation plants.
