Chromite ore is the only commercial source of chromium in the metallurgical industries [1]. It occurs as a chromium spinel, a complex mineral containing chromium, iron, aluminium and magnesium in changeable proportions depending upon the deposit [2]. Chromite deposits can be estimated using geostatistics and geotechnical methods [3,4].Web
