  • Introduction to Mineral Processing

    Froth flotation is considered to be the most widely used method for ore beneficiation In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

  • Cleaning and Polishing Brass

    The only situation, in which it would make sense to remove the oxide layer, would be if you intended to apply a protective layer of paint or lacquer to the surface of the brass Polishing: The method for polishing metals like copper, brass, and steel, is by removing the layer of oxide, which results in a small loss of metal atoms as the oxides.
