The magnetic separation cycle included wet magnetic separation (WMS) with a field induction of 0.18 T on a straight-flow drum magnetic separator in the first stage and high-intensity magnetic separation (HIMS) at an induction of 1.0 T in the second stage. The results of beneficiation are presented in Table 7.
