The borax method of gold extraction has been used by artisanal gold miners in the Benguet area north of Manila in the Philippinesfor more than 30 years. Some believe it was in practice as early as the 1900s. The method is increasingly being seen as a safe alternative to the widespread use of toxic mercury in artisanal gold mining today. About 30 of the world's mercuryes from small scale mining. Efforts are being made to revive the method and spread its use. As of 2012, around 15,000 artisanal go

29/06/2014· This vid is a touch confusing as the Borax is'nt as far as I can see doing any extracting until smelting, seems to be crushed, milled, then sluiced and panned out, then Borax just added to the final concentrate for smelting. I guess in the final concentrate the Borax may help release the Gold out of the heavies better than Mercury can.

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.
The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners.
A group of miners in the Philippines has demonstrated that borax, when used as a flux for smelting gold out of heavy mineral concentrates, is an effective and safer substitute for mercury.

A common substance used is borax. Borax allows you to melt your own gold in a safe, well ventilated area of your home. Use a knife to scoop out the charcoal until you have a small bowl like container. A gold ring or small necklace should fit nicely into the bowl you have created from the piece of charcoal.

Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, ispound with formula Na 2H 4B 4O 9nH 2O or, more precisely, 2 .
The formula is often improperly written as Na 2B 4O 7n+2H 2O, reflecting an older incorrect understanding of the anion's molecular structure. The name may refer to any of a number of closely related boron containing mineral orpounds that differ in their water of crystallizationconten
07/08/2013· With some borax, heat, and a little know how, its 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.
A group of miners in the Philippines has demonstrated that borax, when used as a flux for smelting gold out of heavy mineral concentrates, is an effective and safer substitute for mercury.

The mercury free gold extraction method uses borax in the process of gold smelting. Borax is used in the smelting process because it lowers the melting point of gold and other metals. In this method, the mining of gold bearing ore, the grinding of the mined material and the concentrating from sluicing are the same as in the amalgamation method.
Borax is applied as a flux to reduce the melting point of gold dust contained in grinded ore thus, after a direct smelting process, very pure and mercury free gold is the result. 11,12 Borax is a naturally occurring mineral and can be mined. It is used in many

Gold extraction with borax The use of chemical borax, also known as sodium borate, appears to be one of the more viable ways that have been proposed to reduce or stop the use of mercury by small scale miners Spiegel Veiga 2010. Borax is used for cleaning purposes and ismonly available.
Extraction of Gold using the Borax Process The borax process is also an environmentally friendly method of extracting gold. Here the gold bearing rock material is placed in a melting crucible and then borax sodium borate is added. The borax sinks the melting point of the ore mixture and makes the molten mass more fluid.
12/11/2015· Borax was used to melt the gold and draw out impurities I thought, not draw gold out of any material. The only difference I can tell, between extracting with Mercury and this video just seems to be the absence of Mercury, and substituting it with a trammel, nothing more.
