Abstract
Because of the low ilmenite grade and fine dissemination size, a lot of low-magnetic flaky phlogopite in the run-of-mine ore and it can not effectively remove the phlogopite by the high gradient magnetic separation, so it is very difficult to sorting. We decided take the process of low intensity magnetic separation – high gradient magnetic separation and gravity separation discarding tailing - high gradient magnetic separation and shaking concentrate. Then we obtained satisfaction index - the grade and the recovery of TiO2 were 43.32% and 74.41% in the ilmenite concentrates, the grade and recovery of Fe were 66.83% and 56.77% in the iron concentrates. It provides a feasible way for such ilmenite separation.
