Processes that win and purify metals other than iron, such as aluminium, titanium, nickel, gold, silver and zinc, by chemical, electrical or flotation methods. A member belongs here when the cited article describes it as a process for extracting or refining a non-ferrous metal. The group is one of the groupings under this field in the Technology Atlas, and each member keeps its own entry with its own cited sources and its own place in the field. Its members appear in the Browse By view for the field, so a reader can move from this group to each member entry and to the sources cited there.

Gold cyanidation, Wikipedia
Has Member: Gold Cyanidation, IntroductionQuote, Has Member: Gold Cyanidation, Introduction
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore through conversion to a water-soluble coordination complex.
Heap leaching (Wikipedia)
Has Member: Heap Leaching, IntroductionQuote, Has Member: Heap Leaching, Introduction
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.
Cupellation, Wikipedia
Has Member: Cupellation, IntroductionQuote, Has Member: Cupellation, Introduction
Cupellation is a refining process in metallurgy in which ores or alloyed metals are heated to very high temperatures and subjected to controlled operations to separate noble metals like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony, or bismuth, in the ore.
