Jun 09, 2013· HELP! Does anybody know what formula would make a good gold smelting flux? I am planning on buying a kiln in the near future and the only formula for flux I have found is: 30 grams of ground sample + 30 grams soda (Na2CO3) + 30 grams lead oxide (PbO) + .
The matte is tapped from a hole near the bottom of the furnace and poured into a huge ladle. An overhead crane picks up the ladle and pours the molten matte into another type of furnace called a though it is more than 50 percent copper, if cooled now the metal would be silvery in color because of the relatively high iron content.

Aug 07, 2013· It also plays an important role during the gold refining process as a flux. In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little knowhow, it''s possible to extract pure gold from a sample of ore.
Smelting is a process of applying heat to ore in order to extract a base is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Flux: Flux,, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite.
I would like to know more about flux calculation for gold smelting. I use Borax, Silica flour, Soda ash and Potassium nitrate. Most of my sludge contains Copper, what is the best flux calculation to use say if one have a dried calcine of 95 kg. Please advice on a formula to use on fluxes for dried gold calcine to smelt in an induction furnace.
