Preliminary Study on Floatation of Flotation Column for ...
In order to improve the flotation efficiency of high ash fine coal slime, flotation column was used to study the flotation of slime in Ertang Coal Preparation Plant. Firstly, industrial analysis and sieving test of the floating slime were carried out. The results show that the flotation efficiency is the best when the collector dosage is 400g / t and the amount of ing agent is 600g / t ...

Switching and optimizing control for coal flotation ...
Oct 17, 2017· Flotation is an important part of coal preparation, and the flotation column is widely applied as efficient flotation equipment. This process is complex and affected by many factors, with the froth depth and reagent dosage being two of the most important and frequently manipulated variables. This paper proposes a new method of switching and optimizing control for the coal flotation .

"Coal cleaning by froth flotation " by Choon Han
When a microbubble flotation technique was employed to float Appalachian coal, it produced a cleaner coal product than conventional macrobubble flotation;A general kinetic model was proposed to represent the rate of flotation of coal. For two Appalachian coals, the model successfully represented the flotation kinetics of uniformly sized coal.
