Effect of ultrasonic irradiation on particle size, reagents consumption, and feed ash content in coal flotation
Abstract Ultrasonic waves have a lot of use in the particle surface cleaning. As flotation is one of the methods associated with surface properties, this paper investigates the effect of these waves on performance, particle size, reagents, and feed ash content in coal flotation. To accomplish this g...
