Jul 04, 2019 Wolframite mineral processing method mainly in gravity separation, and includes four parts pre-selection, gravity separation, concentration and recovery. By pre-selection and discarding the waste rock which accounts for 50 of the raw ore, the WO3 grade of the ore is enriched from 0.25 0.3 to 0.45 0.8 , and the recovery is 96 98 .
ore is hoisted to the surface for further concentration. In the mine, workers try to separate the ore-bearing minerals from the barren rock as much as possible during the mining process. In some mining districts, the lead or zinc is found in massive deposits and
