2004. A. The decision on refining gold by a hobbyist is a hotly debated item at best. The first and foremost thing to be considered is the fact that no matter how careful you are, there will always be a good chance that your hobby will kill or cripple you or someone you love.
#0183;#32;i was told that i could make nitric acid by mixing 1qt sulfuric acid +1/2 cup sodium nitrate. i am new to refining and need all the info i can find. i am guessing that i can buy hydrochloric at an auto parts store because i think it is used in car batteries. but i want to buy the acids/chemicals already made to make it as easy as possible during my first few attempts at refining. i have pounds
#0183;#32;The SubZero is just sodium nitrate. Use it where you need NaNO3. AR is not a good choice for steel objects plated with gold. I use hot HCl. This will free up the gold and then you can process the gold foils or powder in HClCl or AR.
Often much of both the sodium nitrate and HCl are wasted because the sodium nitrate remains undissolved.

A SUBZERO GOLD REFINING STARTER KIT Blogger. May 01, 2011#183; A very inexpensive way to refine your scrap gold. The Sub Zero method of gold refining is suitable for karat gold, gold filled, refining bench sweeps, polishing sweeps, computer circuit boards, gold nuggets, alluvial gold and about all other forms of gold.
#0183;#32;If a subzero and HCl mix produces brown fumes when it is dissolving metals, then it is a nitrate salt of some sort. Most likely it will be sodium nitrate because it is very cheap.
Aqua regia dissolves gold, though neither constituent acid will do so alone, because, in combination, each acid performs a different acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au 3+).The hydrochloric acid provides a ready supply of chloride ions (Cl ), which react with the gold ions to produce
#0183;#32;You want about 4/1 mix HCL to sub zero (sub zero is about the same thing as sodium nitrate or nitrate of soda. Two things, P111 CPUs dont have very much gold. You will be lucky to get about .5 to grams of gold from these CPUs, just not much.

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 deliquescent solid very soluble in water.
