Abstract

Abstract:

Two different coal samples were selected to perform traditional mixed flotation and classified flotation respectively and polynomial matching was utilized to build the functions of concentrate yield, concentrate ash content and flotation perfect degree with drug dosage. Through the analysis of this mathematic model it indicated that for Yulong coal sample classified flotation showed obvious advantage while for Wenshang coal sample classified flotation was not effective. Electrostatic interaction between high ash ultra-fine slime and coal particles of different size was analyzed to explain this phenomenon.

Key words: coal slime, classified flotation, polynomial matching, electrostatic interaction, drug dosage
