  • 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 995 percent purity The Wohlwill process increases purity to about 9999 percent by electrolysis In this process, a casting of impure gold isGold extraction refers to the processes required to extract gold from its ores This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small goldGold extraction Wikipedia

  • Understanding efficient process Mining Technology

    “In a lot of ways, gold is probably considered the easiest of the mining industry It uses many of the same processes as other industries, but the key difference is the scale, so it will always come back to the fundamentals, which are reliability, accuracy, and availability They’re the key areas that mine operators are looking for,” explains John Leadbetter, MD of processThe hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation characteristics These are summarisedGold processing 101 Mining Magazine
