Advantages and Disadvantage of Froth Flotation

Froth flotation method is a kind of mineral processing technology that the solid minerals emerge from water suspension (slurry) according to the physical and chemical properties of the mineral surface.. According to statistics, more than 60% ~ 70% ore in the world is separated by froth flotation method, involving more than one hundred kinds of minerals.
