Scheelite Ore Flotation Separation Technique and Influence …
Scheelite often exhibits a complex symbiotic relationship with calcium-containing gangue minerals such as calcite and fluorite. Because the planktonic properties of these gangue minerals are similar to those of scheelite, it is difficult to separate these ores. It can be seen that the effective separation of scheelite and calcium-containing …
