Also known as red hematite rock of its chemical formula is Fe²O³, which is a weekly magnetic iron mineral, magnetite floatability than good, one of the main raw material is iron. The main mineral processing technology have re-election, and strong magnetic separation or flotation process and use a variety of mineral, and there have been post-low intensity magnetic separation magnetic roasting process. Early hematite mineral processing generally use mrock re-election process, mainly jig, centrifugal concentrator, spiral chute, spiral concentrator, shaking and other mineral processing capacity because of their small, beneficiation of low grade, low recovery rate gradually Later, the development of red iron rock out of the flotation process and the high intensity magnetic separation process mainly paraffin oxide soap is for the collector of the flotation process and to electromagnetic annulus Intensity Magnetic Separator for sorting equipment, high intensity magnetic separation process.

But the sorting specifications have not reached a satisfactory result. In recent years, the mineral hematite has achieved rapid development, the main mineral processing technology are: electromagnetic pulsating high gradient magnetic separator is represented by strong magnetic beneficiation process and represented by series of anti-flotation beneficiation process. Especially the use of magnetic – flotation process to make some of mine co-hematite sorting reached grade of iron concentrate and iron rock recovery satisfaction index.

Hematite Iron rock beneficiation process flow
The hematite’s another name is red iron rock, and its chemical structural formula is Fe203. it’s a weak magnetic iron rock and the floatability is better than magnetite. And it is a main material of iron making. The main beneficiation process includes: gravity separation, floatation, strong magnetic beneficiation or mix several beneficiation process and another process is magnetization roasting and then weak magnetic separation. The early hematite beneficiation mostly used the gravity separation process, and the main machines are: jigger, centrifugal separator, spiral chute, spiral washing machine, shaking table etc. Because some other beneficiations’ production capacity was small, the grade after processing was low; recovery ratio is low and then was dumped as time goes on. Later as the hematite beneficiation developing, the floatation process ans high intensity magnetization process.

It mainly uses oxidized paraffinum sodium salt as the collector for floatation and electromagnetic strong magnetic separator as beneficiation equipment for strong magnetic separator. But the others beneficiation technology target were all not good enough. These latest years, the beneficiation process of hematite has developed very well. Especially use the high intensity magnetic separation which is can improve the grade of iron rock concentrate very well, and the recovery of Iron rock concentrate is satisfying.
