CYCLONIC SEPARATION MECHANISM OF CYCLONIC STATIC MICRO-BUBBLE COLUMN FLOTATION AND ITS APPLICATION

摘要

A novel flotation device, cyclonic static micro-bubble column flotation (FCSMC), was introduced in this paper. FCSMC has been widely applied for fine coal preparation in China, and its application has been further expanded to the mineral processing industry. The FCSMC system features a unique cyclonic structure which enhances the separation performance of the column. In this paper, the cyclonic separation mechanism of FCSMC process was investigated, and corresponding kinetics equations were established to probe the separation principle of this device. Some typical examples of using FCSMC to separate different materials including coal, copper, fluorite, etc., were presented.
