reserves of good quality of iron ore. The iron ore of this region is although rich in iron content but suffers from two disadvantages. One is high alumina content in the iron ore and second is softness of the ore which generates huge quantity of fines and slimes during mining and beneficiation. JSW Steel limited operates 3.0 mtpa and

Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total ...


The Iron ore processing plants have been invariably generating slimes in the range of 10 – 15 % of the ROM treated. These losses are in the tune of over 15 million tons of iron values every year. The tailing ponds of most of the iron ore mines are getting accumulated with these slimes and are at the verge of getting filled.
