Hematite beneficiation
The early hematite beneficiation generally adopts re-election process, mainly including jig, centrifugal concentrator, spiral chute, spiral concentrator, shaker, etc. Due to its small ore dressing capacity, low beneficiation grade and low recovery rate, it gradually Be eliminated Later, hematite beneficiation developed a flotation process and a strong magnetic separation process, mainly using a positive flotation process using oxidized paraffin soap as a collector and a strong magnetic separation process using a magnetic flat ring strong magnetic separator as a sorting device. However, its selection technical indicators have not achieved satisfactory results. In recent years, the ore dressing of hematite has made great progress. The main beneficiation process is a strong magnetic separation beneficiation process represented by electromagnetic pulsation high gradient magnetic separator and a reverse flotation beneficiation process represented by series. In particular, the combination of strong magnetic-flotation process has enabled the hematite classification of some mines to reach the iron concentrate grade, and the satisfactory index of iron concentrate recovery rate.
