| Abstract: |
| Gravity Separation Tailings of Watershed scheelite in Australia have WO3 0.45%, which the metal distribution rate is as high as 83.59% in size fraction of -25μm, and it have easy-floating gangues such as carbonaceous minerals and mica, so it is very difficult to be recovery. Test study on recovering scheelite by flotation has been done on this refractory ore sample, ultimately, we get scheelite concentrate of which grade is 59.13% and recovery is 65.72% by collector of BK416 and process of “pre-flotation—flotation at ambient temperature—heating concentration”. |
