separation method is used to separate gold and iron

Gold parting Wikipedia

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

Selective separation of gold from iron ore samples using

Gold in iron ore samples is separated from iron (major matrix cation), antimony and vanadium using anion exchange resin in (0.2 M) HBr, potassium peroxodisulfate and acetone:water:nitric acid media. The exchangeable anion Cl − of the ion exchanger Dowex 1X 4 is replaced by Br − using (6 M) HBr solution.

The Gravity Separation Methods Used To Process Gold?

Gravity separation is one of the common methods for gold extraction, which uses different specific gravity of materials and different settlement velocity in the medium to carry out stratified separation. Generally, when gold mostly exists in the form of monomer natural gold, the density difference between gold and gangue is large, it is more effective and economical for gold separation.
