High-efficiency Separation Process Test of a Lean Magnetite Ore in Northwest China
In order to efficiently develop and utilize a lean magnetite ore resource in Northwest China,based on the detailed study of ore properties,the beneficiation process test is carried out.The results show that the iron concentrate with yield of 13.95%,total iron grade of 65.58%,total iron recovery of 60.32%and magnetic iron recovery of 96.35%can be obtained by the process of conventional crushing-dry magnetic pre-concentration-preconcentrate high pressure roller mill(-3 mm)-wet magnetic preconcentration-stage wet grinding of preconcentrate-stage wet magnetic separation.The recovery of iron minerals is well realized,which can provide technical reference for the development and utilization of iron ore resources.
