The depressant increases the selectivity of the floatation. Complete step by step answer: -The froth floatation process is a method employed to separate the minerals from the impurities by forming froth in which the minerals separates out. -In the froth floatation method, first the surface area of the ore is increased.

22.06.2021Froth flotation is a traditional mineral beneficiation technique. The process involves adding chemicals to a slurry that alters the surfaces of milled particles so that they become hydrophobic. Air in the form of bubbles picks up the hydrophobic particles as they rise to the top of the pulp and form a froth.
