Froth Flotation Size Of Ore

Introduction to Mineral Processing
froth flotation cells The process of froth flotation entails crushing and grinding the ore to a fine size This fine grinding separates the individual mineral particles from the waste rock and other mineral particles The grinding is normally done in water with the resultant slurry called the pulp
