| Abstract: | The domestic and foreign magnetite resources and the current situation of beneficiation are presented. The separation theory and concentration effect of the magnetic field screening method are discussed in detail and a rational technological process of using the magnetic field screening method is put forward. The test results of the final concentration operation, fine screening operation and regrinding and reconcentration process of middling in the concentrator show that the method not only can increase concentrate grade, but also can reduce energy consumption and simplify the process. |
