Column Flotation For Fine Tin Recovery - Sciencedirect

Wheal Jane Tin Mine, South West Cornwall, England processes a fine grained cassiterite ore 0.85 Sn by a combination of gravity concentration and flotation. The material, too fine to be effectively recovered by gravity concentration 70 45 um is deslimed at 4 um and treated by froth flotation to produce a low-grade tin concentrate.

A Review On Reagents And Processes Of Fine-grained ...

Tin resources are abundant and complicated in China. Most of tin resources come from cassiterite. Normally the main beneficiation method of coarse cassiterite ore is gravity separation. However, as for the fine-grained cassiterite, flotation and joint processing techniques are generally selected to improve the low recovery from gravity separation.
