DESIGN AND PERFORMANCE ASPECTS OF COAL

2017-12-20 · Flotation is commonly used to treat fine coal (typically below 500 microns in size) and is a complex, three-phase process that is controlled by factors which can be divided into three facets: coal, chemistry and machine. It is most often used for treating metallurgical coal fines where the value of the product can justify the added treatment cost of cleaning and dewatering the product component. However, because of improvements in flotation
