Reengineering and selective recovery of iron-bearing silicate minerals
The recovery of iron-bearing silicate minerals is a key on the re-separation middlings of Anshan type lean magnetite,but this recovery process should be conducted selectively. The iron grade of stage 1 tailing is only 3.92%,so there is no need to recover
