  • Extracting Gold | HowStuffWorks

    To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls.

  • Extraction of Zinc: Process, Ores, Diagram

     · Roasting is the process of heating a sulfide ore to a very high temperature in the presence of air. This process is generally applied to sulfide minerals. The sulfide is converted to an oxide during roasting, and sulfur is released as sulfur dioxide, a gas. The sulfur dioxide obtained is used in the manufacture of sulphuric acid.
