EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE THROUGH GRAVITY

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%

Although concentration criteria is a useful rule of thumb when predicting amenability to gravity concentration, The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day. This process of
