  • Processing, smelting and refining gold World Gold Council

    The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

  • Gold Smelting Process Sciencing

    Gold is purified by means of a smelting process, which utilizes pressure, high heat and chemicals to accomplish the task. Like any metal that appears naturally in the earth, there are impurities that must be removed. Removing minerals and other impurities allows gold to be used in

  • Gold Melting Furnaces Metallurgist & Mineral Processing

    Gold Melting Furnaces: A few years ago, the spotlight was after creating a microwave kiln for smelting metals and performing fire assays. The first product was a microwave kiln that was quickly followed with the creation of the KK-4 which is called the Kwik Kiln. The KK-4 kit comes complete, minus propane and something to smelt, of course. The Kwik Kiln has seen fantastic success with more

  • Carbon Regeneration Mineral Processing & Metallurgy

    In normal process streams activated carbon is exposed to a variety of chemicals. Organic compounds tend to adsorb readily on the hydrophobic activated carbon, which reduces site availability for gold cyanide. Other compounds such as calcium and magnesium carbonate commonly precipitate on the carbon surface and restrict gold adsorption access. Consequently, the performance of the activated

  • Carbon regeneration liming

    In the gold industry, activated carbon is utilized in CIP/ CIL process to transfer dissolved gold from cyanide leached slurry to elution column where gold is desorbed from the carbon. Each system is indirectly heated, and uses a rotary kiln to process and convey the material through each zone drying, heating, regeneration, and cooling

  • The process design of gold leaching and carbon-in-pulp

    The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation.

  • A Poor Man's Method of Smelting Gold Sciencing

    You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
