Abstract To achieve selective flotation of mineral particles whether by their removal in a froth or by the lessused method of agglomeration specific characteristics of one or more of the mineral species present must be adequately developed

Frothflotation processes are used extensively for the separation of finely divided solids Separation depends on differences in the surface properties of the materials The particles are suspended in an aerated liquid usually water and air bubbles adhere preferentially to the particles of one component and bring them to the surface
