Gold parting is the separating of gold from and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called the advent of coinage, methods had to be invented to ...

 ·  · Mercury is used in gold mining because of its ability to bind to gold to form an alloy which helps separate the precious metal from rock, sand and other material. The alloy — or amalgam — is then heated, often in a shovel or metal pan over an open fire, to vaporize the mercury, leaving behind only the gold. 1 Amalgamation is carried out in different ways, including wholeore and .

Using Borax Flux to Refine Gold

+

 · With some borax, heat, and a little knowhow, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.

In artisanal gold mining, borax is sometimes used as part of a process (as a flux) meant to eliminate the need for toxic mercury in the gold extraction process, although it cannot directly replace mercury. Borax was reportedly used by gold miners in parts of the Philippines in the 1900s. Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to the Arabian ...
