Flotation Of Cassiterite With Modified Fatty Acids

The separation of scheelite and cassiterite can be carried out by electric separation or flotation. During flotation separation, scheelite is captured with fatty acids, and cassiterite is suppressed with water glass. When scheelite contains aluminum, because molybdenum has good floatability, molybdenum ore can be floated first, and then scheelite.
