Gold cyanidation - Wikipedia

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.

Cryogenic Air Separation Process: A brief introduction (PDF)

Membrane separation In this separation process, equipment pumps air into the membrane module and the targeted gases like oxygen and nitrogen are separated based on differences in diffusivity and solubility. For example, oxygen can be separated from the ambient air and collected at the upstream side, and nitrogen at the downstream side.
