Concentration of Indian Chrome Ores by Ore-dressing Methods

Banerjee, S K and Narayanan, P I A (1957) Concentration of Indian Chrome Ores by Ore-dressing Methods. In: Symposium on Mineral Beneficiation and Extractive Metallurgical Techniques, Feb. 1957, NML, Jamshedpur.



Low-grade chrome ores (roughly classified :simple, ferru-giuous, chrome spinel) from different parts of India were subjected to beneficiation studies at National Metall-urgical Laboratory, to determine their amenability to concentration by ore-dressing methods. Simple ores could easily by concentrated by common gravity methods like tabling and Humphrey's spiral, but the chromium/iron ratio in most cases was low due to iron being present in chemi-cal combination in the mineral chromite. Ferruginous ores were subjected to reduction roast and magnestic separat-ion, and high-grade concentrated low in iron-ideal for ferro-chrome, could be produced. Chrome spinels could not be beneficiated to any appreciable extent.
