Ring pulsation high-gradient magnetic separation recovery method

The invention relates to the technical field of magnetic separation processes, in particular to an annular pulsation high-gradient magnetic separation recovery method which comprises the following steps: S1, screening and magnetic separation: primarily screening ore pulp, screening out large-particle ores, and introducing the screened ore pulp into a high-gradient magnetic separator for magnetic separation to recover magnetic minerals; s2, crushing, pulping and secondary magnetic separation: crushing large-particle ores, forming ore pulp again, and performing magnetic separation on the ore pulp in a high-gradient magnetic separator to recover magnetic minerals; and S3, classified collection is conducted, specifically, the magnetic minerals recovered through magnetic separation are collected, and tailing slurry generated through magnetic separation is collected. According to the method, large particles are screened and then crushed and then return to the high-gradient magnetic separator for magnetic separation
