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.These slimes need processing as they cannot be used directly in blast furnaces In the present investigation typical iron ore slime sample containing 59 22 Fe 4 76 SiO2 and 4 57 Al2O3 was taken The desliming operation was carried out by using 2” Mozley hydrocyclone.
