Silver mining is the resource extraction of silver by mining. Silver is found in native form very As with other precious metals such as gold or platinum, newly discovered deposits of silver ore have sparked with major booms for silver and associated minerals lead, mostly in the galena ore silver is most commonly found in.
Bismuth is extracted from its ores by dry, wet, or electro-metallurgical methods, those which occur in the smelting of galena, the carbon reducing any oxide, either sulphur, iron, nickel, cobalt and antimony, and sometimes with silver or gold.
At the present time, cyanide is the most widely used reagent to extract gold from its ores and concentrates. Various options available to recover gold from PLATSOL® leach solutions are also .. remaining silver present in the galena.
