Method for recovering magnetite tailings by using single magnetic separation process

The invention relates to a method for recovering magnetic separation tailings by using a single magnetic separation process. The method comprises the following steps that the magnetic separation tailings with iron grade of 10-12% and magnetic iron content of 1-3% are fed into closed circuit grinding composed of first-stage magnetic separation, a first magnetic separation concentrate feeding cyclone and a tower mill, and closed circuit grinding overflow products with particle size range of 0.046 mm and content of 90%-95% are fed into second-stage magnetic separation; secondary magnetic separation concentrates are fed into a magnetic vibrating concentrator, magnetic vibrating concentrator concentrates are fed into a magnetic field screening machine, products screened on by the magnetic fieldscreening machine are fed to a dehydration magnetic separator, and products screened off by the magnetic field screening machine are returned to the closed circuit grinding; dehydration magnetic separator concentrates are fi
