  • Processing, smelting and refining gold World Gold Council

    The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. 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.

    Smelting gold usually involves high-tech and high-cost tools to perform. Mostly, mining companies do the procedure, which sees one material bonded to or released from another in the presence of extreme heat. However, prospectors, and people at home, can smelt their old gold using some simple steps. All it requires is access to a few common minerals and compounds, and a high heat source ...

  • Gold extraction - Wikipedia

    A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic ...

  • Using Borax Flux to Refine Gold - Manhattan Gold Silver

    2013-08-07  In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it’s possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.

The chemistry of the chemicals that constitute gold smelting ...

  • Smelting and Roasting Ores to recover gold, silver and ...

    The product of melted sulfides is called a matte, and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. The metal in the nails reacts with the metals in the sulfides ...

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

    2017-01-18  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. These fine particles are then heated in a furnace to temperatures above 1064 degrees Celsius the melting point

Primary smelting and refining processes produce metals directly from ores, while secondary smelting and refining ...

  • Ore Refining - an overview ScienceDirect Topics

    The recovery of metals from sulfide-rich ore bodies proceeds through a series of steps: from mining to crushing to mineral recovery (i.e., concentration), followed typically by smelting of the sulfide concentrates and thence to metal refining; although the nature of the ore body dictates the processes used to extract metals from ores, each of these steps generates a waste stream. The volumes ...

  • Copper extraction - Wikipedia

    Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the copper-containing minerals. However, as the concentration of copper in the ore bodies decreased, the energy ...
