Borax. A white crystalline mixture which is in powdered form at room temperature. Borax helps to lower the smelting point temperature of the ore. This means that lower temperatures that smelting will occur quickly and allow the precious metal to settle out. Also, Borax is
07/08/2013#0183;#32;With some borax, heat, and a little knowhow, 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.
16/01/2013#0183;#32;Melting fine gold with borax from our hardrock ore milling process using an oxygen acetylene torch and borax in a crucible. I forgot to mention in the video

22/05/2018#0183;#32;Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass which will have floated to the top during the cooling process and there is your gold, smelted to perfection.
Borax For Gold Extraction mariniersqpo. Gold extraction using borax page 1 general 29, 2014 this vid is a touch confusing as the borax isnt 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.
17/10/2011#0183;#32;Learn how to make more gold with borax instead of mercury. Description of a new environmentally beneign gold extraction method which will make use of mercury...
Borax method Wikipedia
12/11/2015#0183;#32;But Borax wasn''t used to extract the gold, not at any point, extraction was done by trammel and panning so far as I can tell, but then again I have only read about gold extraction and watched video''s, so far to date I have only recovered and refined. Borax was used to melt the gold and draw out impurities I thought, not draw gold out of any
Method of Gold Extraction using Borax Small Scale Miners No Mercury. Eliminate Mercury using this method of gold extraction with borax for smallscale miners allows for fine gold recovery and better smelting.
Extracting Extracting Gold The Borax Message. 201129borax and its many uses this is the most crucial borax information and yet reports about borax safety give a rather mixed messageeres what ive gleaned about borax safetyink for indelible pens and is more recently being used in place of mercury for extracting gold in smaller scale mining operationsn some countries borax is.
The mercuryfree gold extraction using borax has successfully been tested on a variety of gold ores in Philippines, Indonesia, Tanzania and Bolivia. Recently a successful gold extraction using the method in Zimbabwe was carried out (Stephen BoeseOReily personal communication).
The Borax Method of Gold Extraction for SmallScale . #183; An obvious drawback of this method is the toxicity of, 3 The health risk of mercury is well known today in many parts of the world, but in remote smallscale mining (SSM) communities that knowledge is still Gold extraction by amalgamation releases large
to use borax for gold extraction, significantly reducing global mercury pollution. Methods . Gold capture, as well as the amount of mercury released into the environment, was analyzed for two amalgamation methods and the borax method. The Amalgamation Methods . Mercury is used in gold mining because of its ability to bind to gold
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.
It is known, for example, that the mineral borax, Na 2 B 4 O 7 #183;10H 2 O, can be used either as a solder [23] or as a simple means to extract gold from ores [24]. The property of borax to bind
12/11/2015#0183;#32;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.

In gold refinement, Dehybor #174; anhydrous borax is used in flux formulations to dissolve metal oxides and as a flux in gold assaying. The addition of Dehybor to the smelt is generally 1050% of total smelt weight, depending on the process. The borax contribution to flux composition can be up to 60% of total flux weight but is typically around 3040%.
