    03.04.2005· 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 carbon, or both. Sulfide minerals are impermeable minerals that occlude gold

  • 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. In this process, a casting of impure gold is lowered into an electrolyte

  • Upgrading low grade gold ore stockpiles Mineral

    Sensor-based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and sub-marginal grade material from crushed and screened run of mine (ROM) ore, producing a coarse (typically >10 mm) upgraded pre-concentrate at an early stage in the mineral processing circuit. This avoids additional energy intensive downstream processing of this rejected

    Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation. This relies on the difference in densities between the ore minerals and the gangue

  • 9 Step Process for Discovering, Mining & Refining Gold

    Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step #8 – Refining (off-site) Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out. Crude gold is melted and treated with chloride

    Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption . Free-milling gold can be further classified into low grade and high grade which helps determine the most
