    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 …

    One of these is the addition of granular activated carbon to the ore slurry during or upon completion of gold solubilization. The dissolved gold is readily adsorbed onto the carbon, thus removing it from solution, and the granular carbon is separated from the now barren ore by running the slurry through a screen.
