Refining Gold With Sodium Nitrate Sodium nitrate ratios fo AR help please!!! Gold Refining . As seen on the Karat DVD it took 3 1/2 teaspoons of Sodium nitrate prills to dissolve the 35+ grams of gold. Phil has already quoted my previous posts on the stoichiometrical ratios for sodium and potassium nitrate.
Refining Electronic Scrap Can''t get nitric acid any more. A discussion started in 2006 but continuing through 2018. ... but sodium nitrate or nitrate of soda found at most garden suppliers works just as well. ... I want to start gold refining from electronic scrap as hobby. Currently I can buy nitric acid 68% HNO3.
recovery of gold,silver and platinum group metals (it is best to recover platinum group metals in a cls electrolitic tank) refining silver. if you need supplies go to our store enter the store ... tip=sodium nitrate is hard to desolve in liquids other than water. with that said the mixing goes alot faster if you add 1 cup distilled water for ...
An alternate method is to dissolve 1/2 pound of Sodium Nitrate (Nitrate of Soda 160000) in 16 oz. of HOT distilled water and then add the quart of Hydrochloric Acid to the Sodium Nitrate solution. Usually (but not always) a salt will form rather quickly and settle to the bottom.
Sodium nitrate is used as an ingredient in fertilizers, explosives, and in solid rocket propellants, as well as in glass and pottery enamels; the compound has been mined extensively for those purposes. Sodium nitrate is commonly used in gold refining for making aqua regia which is used for recovery of gold, platinum and other precious metals.

May 14, 2017· HNO3 as a gold recovery chemicals: Full name of HNO3 is Nitric acid. It is also known as aqua fortis and spirit of niter. Pure nitric acid is colorless but an older sample can be yellow cast due to decomposition into oxides of nitrogen and water. For gold recovery, it is using commercial grade concentration 68% in water.

Sodium nitrate is commonly used in gold refining for making aqua regia which is used for recovery of gold, platinum and other precious metals.
While this guide is focused on gold refining, aqua regia will also work for platinum, and includes tips for refining types of platinum. Whether you''re refining gold using nitric acid, sodium nitrate, or MX3, the procedure is essentially the same and pretty simple and straight forward: Metal is dissolved into solution.

We also have all of the chemicals you need for refining, including both chemical compounds and mixtures developed by Shor RD (such as Quadratic and MX3), complete chemical kits like the Aqua Regia Starter Kit, as well as the more common chemicals such as sodium nitrate and sodium metabisulfite. All at very competitive prices.
Often much of both the sodium nitrate and HCl are wasted because the sodium nitrate remains undissolved. For a compound that dissolves faster completely, ... Products in Gold Platinum Refining by the Acid Method. Shor AR3G Aqua Regia Gold Platinum Refining System AR2G Gold Platinum Refining System
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)
