Flotation Of Cassiterite With Modified Fatty Acids

Flotation Of Cassiterite With Modified Fatty Acids

Flotation is an indispensable way to recover the fine cassiterite particles which are lost in gravity separation tailings . Fatty acids were reported in the 1930s as the earliest collectors used in cassiterite flotation . However, the selectivity of fatty acids is too poor to separate the cassiterite from gangue minerals .
