Precious Metal Refining Process

Gold Refining. Gold mines process ore using various techniques to produce an alloy composed primarily of gold and silver, which is called a dore bar. The composition of dore can vary significantly between mines, but generally the gold dore bars the Perth Mint processes are composed of between 7080% gold and 1015% silver.

Electrolysis and Electroplating

An important use of electrolysis is in the production of metals like aluminium, sodium, calcium, magnesium; or even the purifiion of metals like copper, gold and silver. These days the electrolysis of water is used in the production of hydrogen for fuel or generation of electricity using fuel cells.

Refining GoldRefining Gold

Refining Gold

­The final stage of gold production refining involves removing impurities that remain after the smelting companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for .

 · Gold has many uses in the production of glass. The most basic use in glassmaking is that of a pigment. A small amount of gold, if suspended in the glass when it is annealed, will produce a rich ruby color. Gold is also used when making specialty glass for climatecontrolled buildings and cases.

Gold CyanidationGold Cyanidation

Gold Cyanidation

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

Cyanide Use in Gold MiningCyanide Use in Gold Mining

Cyanide Use in Gold Mining

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

Wohlwill process The electrolytic method of gold refining was first developed by Dr. Emil Wohlwill of Norddeutsche Affinerie in Hamburg in 1874. Dr. Wohlwill's process is based on the solubility of gold, but the insolubility of silver, in an electrolyte solution of gold chloride (AuCl 3) in hydrochloric acid.
