Porphyry copper depositWikipedia

Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages circulating meteoric fluids may interact with the magmatic

Processing smelting and refining gold World Gold Council

When gold dissolution is complete the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore) cyanidation is accomplished by vat leaching which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Low Sulphidation Epithermal Gold Deposits
