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

    Jan 18, 2017· Here are the major steps you should follow when smelting gold: 1. Gold Processing . The first step in gold smelting involves processing the gold ore. The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together. The gold ore is then pulverized using pressure to create very fine particles.

  • Gold Cyanidation Ground Truth Trekking

    Process. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually takes place inside a mill or other mining facility.

  • Refining Gold | HowStuffWorks

    ­The final stage of gold production refining involves removing impurities that remain after the smelting process. Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals.

  • The Basics of Successful Gold MiningPart 1

    Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the "paystreak". Paystreaks always form along the gold path where the river's flow slows down on a large scale during a major flood storm.

  • How Is Gold Processed? |

    How Is Gold Processed? Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide ...
