In addition the working principle of froth flotation process also determines that it is complex and rigorous than the other two froth flotation processes In the whole process of flotation grinding fineness pulp concentration pulp acidity pharmaceutical system gas and stirring flotation time water quality and pulp temperature are
Froth flotation is a commonly employed process for concentrating minerals from ores In a flotation process the ore is crushed and wet ground to obtain a pulp A frothing agent usually employed with a collecting agent is added to the ore to assist in separating valuable minerals from the undesired or gangue portions of the ore in subsequent

Froth Floatation Process Principle The principle of froth floatation is that sulphide ores are preferentially wetted by pine oil whereas the gangue particles are wetted by water Collectors are added to enhance the non wettability of the mineral particles

FLOTATION PROCESS FOR EFFICIENT COAL RECOVERY Froth flotation is a widely used cost effective particle separation process However its high performance is limited to a narrow particle size range e g between 50 m and 600 m for coal and between 10 m and 100 m for minerals Outside this range the
