Studies were undertaken to beneficiate a low grade indigenous chromium ore of Muslim Bagh, Balochistan, Pakistan using high intensity dry magnetic separation (HIDMS) technique. The different parameters of magnetic separation such as intensity of the magnetic field, particle size of the feed, feed rate and number of operations were optimized to obtain maximum grade and recovery of chromium. The ore containing 28 % Cr2O3 was upgraded to a concentrate assaying more than 40 % Cr2O3 with 90 % recovery. The final concentrate produced met all the specifications of the chemical grade chromite concentrate.
