The progress and review of fine coal pulp-mixing technology

Abstract

Pulp-mixing operation is the premise and safeguard to achieve effective mineralization and separation. According to the present difficulties in slime flotation, the paper provided that pretreatment of pulp-mixing could be effective. With added force, the particle dispersion and surface modification could be achieved. Under good conditioning, the problems of high ash content and low coal recovery rate would be solved. From the high efficient slime water slurry blending, the paper introduced the study progress of the mixing technology and theory for the slime water slurry and introduced the application and existing problems of the available slime water slurry blending equipment. Through the discussion of present pulp-mixing technology, research status and difficulties, high efficient slime water slurry blending equipment should be developed in order to meet the requirement of the fine and difficult preparation slime flotation technique. Based on the above discussion, it pointed out that high-efficient pulp-mixing technique is a new research direction of mineral processing technology in future.
