FLOTATION

A solids-liquid or liquid-liquid separation procedure, which is applied to particles of which the density is lower than that of the liquid they are in. there are three types: natural, aided and induces flotation.This process works in dissolving unwanted materials and separating them from precious minerals by giving them reason to accumulate into the surface of a froth layer. As a result, this method of grinding will disconnect individual mineral particles from others, including from waste rocks.
