In response to the problem of high direct beneficiation cost for a very poor vanadium titanium magnetite ore in Panxi,based on the identification of the occurrence status of valuable elements and the distribution characteristics of useful minerals in the ore,a classification grinding strong magnetic separation process was adopted for coarse tailings separation.The continuous experiment was expanded to obtain a coarse tailings separation concentrate with a yield of 63.12%,TFe and TiO2 grades of 22.85%and 12.45%,and recovery rates of 80.75%and 84.60%,respectively,The mineral content of titanium magnetite and ilmenite in the crude concentrate is 18.13%and 21.95%,respectively.The recovery rates of titanium magnetite and ilmenite minerals are 95.82%and 91.23%,respectively,effectively achieving the comprehensive recovery of iron and titanium minerals in the vanadium titanium magnetite.
