chromite in the preparation of charge-chrome, it seems that some low cost oriented beneficiation process may be an economical endeavour for up-grading the so far rejected chromite ores. Keeping this in view, in the present investigation, some very low grade chromite samples were taken for laboratory scale beneficiation.
