Sodium nitrate - Wikipedia

Sodium nitrate is the chemical compound with the formula Na N O 3.This 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 nitrate.The mineral form is also known as nitratine, nitratite or soda niter.

The invention relates to modifications of a non-ammoniacal thiosulfate process of leaching precious metals (e.g. gold or silver) from precious metal-containing ores. The process involves leaching the ore with an aqueous lixiviant containing a soluble thiosulfate other than ammonium thiosulfate, a copper compound and an organic compound that serves as a copper ligand (i.e. a ligand-forming ...

Nitrates - Meats and Sausages

The Nitrate is the Mother that gives birth to the Baby (nitrite). Pure sodium nitrite is an even more powerful poison than Nitrate as you need only about ⅓ of a tea-spoon to put your life in danger, where in a case of Nitrate you may need 1 tea-spoon or more. So all these explanations that nitrite is safer for you make absolutely no sense at all.

How silver is made - material, making, history, …

In this process, ore was heated with rock salt, producing silver chloride, which was leached out with sodium hyposulfite. Today, there are several processes used to extract silver from ores. A method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores.
