EFFECT OF KEY VARIABLES ON COAL CLEANING BY FROTH

In this method of wet cleaning, froth is made in a flotation cell by bubbling air through water in presence of frothing agents; on addition, pure and light coal adhere to air bubble while the dirtier part sinks to bottom of the cell. Thus clean coal is recovered from the collected froth amount.
