A Review on Reagents and Processes of Fine-Grained Cassiterite Flotation in Mining Engineering

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. This paper outlines different kinds of cassiterite, collectors and depressants for cassiterite flotation and their using conditions and some reinforced methods in beneficiation of the fine-grained cassiterite for reference in mining industry.
