Magnetic separation of weak magnetic iron ore containing magnetite

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%.
