Iron oxide ores usually follow a processing path where the copper is leached from the surrounding rock. The ore is first heaped into piles in special leaching areas, and a sulphuric acid solution is sprayed over the heap to gradually dissolve the copper, separating it from the surrounding gangue.

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 ...

Current copper deposits contain significant amounts of secondary non-sulphide minerals and newly discovered deposits are increasingly complex. As a result, research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged.

In treating copper–gold ores, a sufficient free cyanide concentration is typically maintained to encourage the selective adsorption of gold over copper onto carbon (other than for the processes described in the previous section, which aim to minimize the dissolution of copper). To recover copper cyanide and free cyanide using carbon the solution speciation therefore needs to be modified to ...

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid left is a mixture of copper sulfides and iron sulfides.
