  • Explaining the Process of Froth Flotation

    The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore usually the valuable ones are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which are floated are
