The study and practice of cyclonic mirobubble flotation column in ash and pyritic sulfur rejection from coals

摘要

The operation principle and the structural feature of a new type of cyclonic micro-bubble flotation column are introduced. The reseults of related laboratory research an industrial investigations are also presented in this paper. It has been proven that this flotation column permits coal desulfurization and ash reduction. It has the potential to substitute the flotation equipment used at present.
