Abstract

The reagent flotation of regular coal by means of liquid containing gas microbubbles is considered. Various sequences of microbubble supply to the flotation chamber are tested and characterized. The supply of gas–liquid microbubble mixture to coal pulp that has previously been dosed with collector proves most effective.
