  • Gold Smelting & Refining Process
  • The Gold Smelting Process Melting, Smelting & Refining

    Jan 18, 2017· Gold miners have to smelt their gold in order to remove impurities resulting in pure gold. Most large scale gold miners send their ore to smelters with large equipment for the smelting process. Small scale miners still can do their own smelting using specialized kilns. Many people confuse gold smelting with melting.
