In this article, attempts made to evaluate the performance of ultra-fine beneficiation circuit in terms of silica reduction in the concentrate of chrome ore beneficiation plant (COB), India are discussed. The approach adopted and practical problems encountered during the study were also discussed.

The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr2O3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.

The magnetic separation process of chromium ore is relatively simple. After simple crushing and grinding, it can enter the separation process. The selection of crusher can be determined according to the customer's own situation. Rod mill is usually used as grinding equipment to avoid over grinding and the decline of beneficiation index.

3. Commercial chromite ore beneficiation processes Pure chromium is difficult to produce since it is readily contaminated by many other elements. Huge quantity of raw chromite ore is being mined and beneficiated in various chrome ore beneficiation plants throughout the world to cater the customized needs of various ferro alloy plants.
