  • Mercury Amalgamation

    Amalgamation is a concentrating in which metallic or , or an alloy of the two, is mixed with mercury, either in a amalgamation drum, or on a amalgamation table, where the precious metal bonds with the mercury to form the metal laden mercury AMALGAM and the waste barren ore pulp are caused to travel different paths to effect

  • Gold parting

    The very earliest attempts at refining gold can be shown by the surface enhancement of gold rings. Gold quality was increased at the surface by 80–95% gold compared to 64–75% gold at the interior found in Nahal Qanah Cave dated to the 4th millennium BC. Further evidence is from three gold chisels from the 3rd Millennium BC royal cemetery at Ur that had a surface of high gold 83%, low silver 9% and copper 8% compared with an interior of 45% gold, 10% silver and 45% copper. The surface was compacted an
