Abstract: 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 it. However,the iron grade of stage 2 tailing is 34.51%,thus this tailing can be returned to the mixing process before direct reduction and its iron is indirectly recovered. Under the condition of the direct reduction temperature of 1150℃,the direct reduction time of 45 min,the limestone dosage of 16% and the coal dosage of 12%,the optimum TFe and εFe obtained from closed-circuit experiment is 92.69% and 91.17%. Iron and silicon in the iron-bearing silicate are reduced to elemental iron and reengineered to aedelforsite,respectively.
