Aug 07, 20130183;32;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.

May 22, 20180183;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.

The flux is a mixture of several reagent chemical such as borax, silica, sodium nitrate, sodium carbonate and fluorspar. Borax is a white crystalline mineral used in glass and ceramic enamel mixes. In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must be controlled; otherwise the slag will be extremely hard and

Nov 12, 20150183;32;For ore nitrates can be used as an oxidizer in the flux to oxidize metals in the smelt, helping to separate them from the gold which will not oxidize, letting the base metal oxides mix with the slag glass from the borax (and sand or glass used), this of course would be best done in a furnace.

The melting point of gold is 1063 C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery
