This paper expounds the necessity of using fast floatation method to guide the production,introduces the floatation principle and its applicability,and points out some items needing attention for applying fast floatation method in coal preparation.

The ap- plication of high-alkali potential adjusting and controlling and high-alkali speed flotation have improved the technical and economic indexes of Fankou Lead-zinc Mine.

The principle flowsheet consist of speed flotation to obtain lead and zinc concentrat in high quality;lead and zinc middle product mixed,after finegrind,was treated in luck flotation to obtain lead and zinc bulk concentrate.

By a reasonable scaled-down system in Jinyang coal preparation plant, this paper analyzes factors affecting the production of re-referral coal preparation guided by clean coal faster floating and concludes the feasibility production of re-referral coal preparation guided by the linear relationship between faster floating and fast floating ash.

Fixing flash flotation test scenarios by examine grindstone process and unite stone nature.

Based on the characters above, Some effective selective collectors such as AP or BJ, were used for fast-flotation orpart-selective flotation.

With help of AP, an original bulk flotation flowsheet was changed into a new fast-flotation flowsheet, a high-grade copper concentrate can be obtained in fast-flotation operation, and final copper concentrate grade and Mo recovery were increased respectively.
