2009/9/30Hi all, I got a powder from a supplier which they give no information on what chemical it is. It is white powder, use as final flux when melting to make gold shinny. What I believe is it is some kind of arsenic. The supplier claim it is illegal to obtain (I'm in Thailand) The flux protects the crucible, allows plasma arcing to occur, and refines the gold processed to a higher degree of purity. When firing, black sands concentrates, iron oxides, etc. are held in suspension by the flux so that the precious metals can be separated and poured into the mold as liquid metal.

The flux lowers the melting temperature of gold, making the process somewhat easier to complete, and the lead helps to collect the pure gold from the alloy. The Refiner Heats the Sample This mixture of gold and other additives is then heated and melted at a temperature between roughly 1000 and 12000 degrees Celsius.

Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make

2016/1/1Primary gold and silver refiners include the larger precious metals companies, such as Asahi Refining, Elemetal Refining, Metalor Technologies, Rand Refinery, and The Royal Canadian Mint. Some smaller refineries also carry out their own chemical refining operations, albeit on a more limited scale, but these companies tend not to be active in the dor business.

How Scrap Gold Refining Works – Best Site to Sell Gold

The gold and slag are heated together to a very high temperature, 1064 degrees centigrade, to make it melt. This liquid is then poured into molds and allowed to cool into bars called buillion. In the process of cooling, the flux and the impurities that have bonded to it separate from the gold and float to the top, which enables the precious metal refiner to determine the amount of gold that is

If the gold flakes are pure refined gold, no flux is needed. * Most metals form oxides during melting and require some method to prevent oxidation ( vacuum furnace or oxygen scavenger cover) or other methods to separate the oxides from the melt( f

The two most common methods of refining gold are refining with flame and the use of chemicals. There are actually a few different methods of refining gold. Depending upon the quantity of gold you are working with and the desired level of purity, the two most common methods for refining gold are the use of high temperature flame and the use of chemicals to refine the gold.
