  • Froth flotation

    The process proved successful at their Central Block plant Broken Hill that year. Significant in their agitation froth flotation process was the use of less than 1% oil and an agitation step that created small bubbles which provided more surface to capture the metal and float into to a froth at the surface.

    Flotation separation of scheelite from calcite is difficult due to the similarities in their surface properties. In this work the flotation behavior of scheelite and calcite using oxidized paraffin soap (OPS) benzohydroxamic acid (BHA) and the mixed OPS/BHA collectors was investigated through micro flotation experiments.
