  • Gold Refining Process Mineral Processing amp Metallurgy

    gold occurring in the alluvium is not refined by any of Natures processesbut the accompanying minerals or metals are either oxidised or removed hence, in the recovery of gold from reefs impurities are often collected and introduced, thus making it of lower value than the corresponding alluvial gold, and also giving rise to erroneous

  • How Is Gold Processed? Reference

    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
