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 %.

wolframite grains varied between 10 and 200 μm, and an average size was 50 μm. About 15% occurred as coarse inter-granular grains. Very fine grains with 10 to 15 μ m size constituted about 15% as inclusions within quartz. According to the ore mineralogy, fine grinding was required to obtain a reasonable liberation.
