Beneficiation of a Low Grade Titanomagnetite Ore in Mining Engineering

Abstract:

Beneficiation of a low-grade titanomagnetite ore containing 18.52%Fe and 6.65%TiO2 was conducted by dry and wet low intensity magnetic separators. Effects of different variables, such as magnetic intensity, grinding fineness and stages of separation, were investigated in details. The ore was firstly preconcentrated by a dry low-intensity magnetic separator (DLMS) at a magnetic intensity of 2500Oe, and then ground to -0.074mm 53%, followed by a wet low-intensity magnetic separator (WLMS) to recover iron minerals. An iron concentrate assaying 49.22% Fe can be obtained at a recovery of 46.23%. The concentrate was further ground to -0.074mm 70%, followed by two stages of WLMS, and a marketable iron concentrate assaying 56.24% Fe and 9.44% TiO2 can be obtained at the recovery of 42.89% and 20.69%, separately. Tailings assaying 6.48% TiO2 with a recovery of 79.31% is subject to be further recovered.
