| Abstract: | Great difficulties existed for recovering tungsten by flotation at ambient temperature from certain tungsten ore highly containing fluorite and calcite in Yunnan.According to the properties of the ore,the technological flowsheet of selective flotation of sulfur-flotation of scheelite at ambient temperature was adopted,and FW,as a new collector for scheelite,and sodium silicate as the modifier in the cleaning process were used to recover scheelite.The scheelite concentrate with grade of 51.78% and recovery of 81.44% was obtained from raw ore containing 0.32%WO3. |
