Froth flotation is a universally accepted process for the beneficiation of coal fines, but the process being sensitive needs careful monitoring of the process variables. One of the

Coal beneficiation technology to reduce hazardous

2021-4-20  The particles under 0.5 mm are beneficiated through froth flotation, which employs small air bubbles and separates the clean coal from the mineral matters based on the difference in the components’ hydrophobicity.Froth flotation is relatively expensive than the density-based separation beneficiation processes. Therefore, it is only employed in metallurgical coal processing plants due to
