The invention discloses a beneficiation method for scheelite. The beneficiation method comprises the step of floating scheelite by taking oleic acid as a collecting agent and a foaming agent under the condition that the PH value of ore pulp is equal to or larger than 10.8. By using the method, the scheelite can be beneficiated at high yield.

Scheelite sorting method can re-election, magnetic separation, flotation. Different types and nature of the ore beneficiation methods and processes used are different. But based on scheelite good floatability, more due to the presence in the ore of a similar nature to their gangue minerals calcium, which led to the flotation of complexity.

Moreover, the amount of valuable minerals in HT depends largely on the initially employed beneficiation methods and their efficiencies. For instance, for high density ores such as scheelite ores, gravity separation and flotation methods are conventionally used, and depending on the associated minerals, magnetic separation may also be used .
