    The processes of thermal metallurgical treatment of metallic ores and concentrates to accomplish the recovery of the metals consist of three general divisions or steps:

    1. Roasting of the ores or concentrates.

    2. Smelting of the ores or concentrates:

    (a) Reduction to matte followed by conversion of the matte to crude metal.

    (b) Direct reduction to the crude or refined metal.

    3. Refining of the crude metal.
