Coal Flotation Machine

Jan 01, 1995 The present invention is directed to a type of flotation machine that combines three separate operations in a single unit. The flotation machine is a hydraulic separator that is capable of reducing the pyrite and other mineral matter content of a coal. When the hydraulic separator is used with a flotation system, the pyrite and certain other

Coal flotation as a rate process | SpringerLink

The goal of this study is to evaluate the coal flotation process and the interaction of the chemical (reagent) and hydrodynamic (machine, operational) variables as they affect yield, flotation of various sized particles, and sulfur and ash rejection. Coal flotation is found to follow a first order process with the coal floating much faster than either pyrite or ash. This circumstance may be

Clean Coal Dewatering: The 13-0.5mm clean coal in pit is first dewated by bucket elevator, secondly dewated by centrifuge machine, and then transported to the clean coal storage yard by belt conveyor as the final product together with the clean coal on the screen. Flotation: The overflow from the pit enters the flotation feed pool and is pumped to the pulp preprocessor through the slurry pump
