  • How do we extract minerals? | Geological Survey

    The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods.

  • Extraction of Zinc

    Roasting: After the concentration of ore, the next step involves the extraction of zinc by Roasting. The concentrated ore is finely divided into small pieces and is then suspended in a rising stream of air. The sulfur content can be reduced hugely with this process. This also converts the Zinc blende to ZnO which is more reactive.
