Abstract

Abstract:

The importance of conditioning as the start process in fine coal flotation is introduced. New methods and equipment in this area are summarized and reviewed. Some prediction and suggestion are given about the development trend of conditioning technology and equipment. On this basis, it is indicated that the mechanical agitation theory of conditioning, such as high intensity conditioning (HIC), multi-stage conditioning and multispindle conditioning, continues to be further developed and richen; new conditioning methods, such as pressurization, electrochemical and ultrasonic treatment, are constantly introduced; conditioning equipment upgrading is inevitable and some new equipment emerges, but most currently equipment is mechanical agitation type. Before the industrialized application of other new conditioning methods, further theoretical research and demonstration is necessary.

Key words: flotation, conditioning, preprocess, mechanical agitation, high intensity conditioning
