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

摘要

The operaiton principle and the strucutural feature of a new tyep of cyclonic micro-bubble flotation column are introduced.The results of related laboratory research and industial investigations are also presented in this paper.It has been proven that this flotation column permits coal desulfurizaiton and ash reduction.It has the potential to substitute dthe flotation euqipment used at present.
