EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE
Fatma et al. (1999) studied the beneficiation of an iron ore sample containing 44% Fe, 1.59% SiO 2 and 20% BaO. By magnetic separation, two products of iron ore and barite concentrates were obtained by using a high intensity magnetic separator. The fine fraction (-0.125 mm) is about 20% by weight assaying 54.6% Fe, and 3.91%
