Utilization of high-gradient magnetic

2019-6-1  Secondary grinding is necessary to destroy the gangue structure. Although secondary grinding will increase the cost, the magnetic-concentrate yield is 22.03% (for raw ore) with a recovery rate of 31.10%. The magnetic concentrates have a high recovery rate, and less mass, so the grinding consumption is lower.
