gold refining using sodium nitrate One of its advantages is that this reagent, if melted in with the fine gold, will cause no trouble; sodium nitrite is chemically related to sodium nitrate, and the latter, often called Chile saltpetre, is used as a flux and purifier when gold is melted. .

The Inquartation method is one of the most common method of refining low karat gold jewelry (9K14K) and silver such as sterling silver... Inquarting don''t usually applied for high karat gold jewelry (18K22K) since they have low silver content and can be dissolved directly with Aqua Regia.

The preferred salt is usually Sodium Nitrate. The chemistry behind AR is a bit more involved then you might expect, so we will just go over what is necessary for us to understand the process, in simple terms. In Aqua Regia, the Nitrate ions serves as an oxidizer where the Chloride ions act as sort of "receptors" and accommodate the oxidized metals.

Sodium nitrate is the chemical compound with the formula Na N O alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) to distinguish it from ordinary saltpeter, potassium mineral form is also known as nitratine, nitratite or soda niter.. Sodium nitrate is a white solid very soluble in water.

Often much of both the sodium nitrate and HCl are wasted because the sodium nitrate remains undissolved. For a compound that dissolves faster completely, ...

also with aquaregia you are desolving the gold,so there are alot of variables that can cause loss of your gold. my system uses a safe nitric sustitute. here is how you can make the acid. in a widemouth gallon glass jar or glass jug pour in 1 quart of sodium nitrate. add 1 to cups of water and let it sit overnight.(12 hours)

Sodium Nitrate. Some types of flux are good at oxidizing specific metals. Sodium Nitrate belongs to this class of flux elements. Sodium nitrate oxidizes metals like iron, copper, and zinc by liberating oxygen at a temperature of about 500oC. ... Thereby lowering the value of the eventual product of the gold refining process. 7. Conclusion.

Refining large quantities? See: Large Scale Gold Refining by Aqua Regia Acid Method. Having described its hazards, it must be pointed out that, like most industrial processes, refining gold in acid is quite safe when performed under controlled conditions. In addition, the results of doing your own refining can be quite lucrative.

Feb 27, 2016· 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 ...
