design and performance aspects of coal flotation - Jameson Cell
ABSTRACT. 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...Read More
