Study on the Mineral Processing of Cassiterite from Flotation Tailings by a Combined Method

Abstract:

A tailings assaying 0.4% Sn is taken from a flotation process which is used to recover Cu, Pb and Zn. The cassiterite in the tailings is of fine dissemination and complex composition, which leads to difficulties to recover by traditional gravity concentration. In order to enhance the recovery of Sn and make good use of the tailings, particle size analysis and chemical analysis were conducted. Test results show that different flotation index under different size range can be obtained, and the flotation behavior of different size range was investigated. As a result, a reasonable process of gravity concentration and flotation after classification is proposed, which can enhance the Sn recovery remarkably.
