Aug 07, 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.
The borax contribution to flux composition can be up to 60 of total flux weight but is typically around 30-40. Borates are also used to facilitate the attack of gold ore at a lower temperature and to make the slag more fluid at the furnace operating temperature, thus reducing viscosity. The benefits of Dehybor in gold refining are numerous
