  • Projects — Missouri Cobalt

    Missouri Cobalt has completed commissioning on its new froth flotation facility the Madison Mine Processing Plant (MMPP). Froth Flotation is the most widely used method for ore benefaction whereby valuable minerals are separated from other non-valuable minerals by inducing them to gather in and on the surface of a froth layer.
