At present, there are some strong magnetic beneficiation plant applications directly separator sorting hematite or hematite artifacts, it proved that this is a good effective method. For example, a mineral processing plant processes ore containing magnetite and hematite, and uses a weak magnetic field magnetic separator and a strong magnetic field magnetic separator to recover magnetite and hematite, respectively. Its industrial test process is shown in the figure. The index achieved by this process is: when the ore grade is 34.20% Fe (FeO 3.7%), the concentrate grade reaches 56.46% Fe, and the recovery rate is 78.95%.
