Borates in Metallurgy and Gold Refinement

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...

Smelting flux recipe notes from a large gold mine

Slag after melting pins

Sep 12, 2013 0183 32 I expected the most of the button to be copper and the gold has sunk to the bottom, but when I started filing the black slag it appeared, that there was also gold underneath I remelted the button with a torch propane/butane and let it melt completly Same effect, nice gold on teh bottom but a black coating all over...

How to Choose Gold Smelting Flux

After this, the gold and silver alloy settles to the bottom since it is heavier while the slag floats and is taken off Despite these extreme conditions, however, it still remains difficult to separate out some impuriti It is often the case that some of the gold gets trapped within the slag which floats...
