The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1.

Chromite ore is predominantly used in the production of ferrochrome – an alloy of chrome and iron containing between 50% and 70% chromium. The production of steel is the largest consumer of ferrochrome, especially stainless steel production which contains between 10% and 20% ferrochrome content. The process of chromite ore mining can be ...
