Primary copper sulfide minerals such as chalcopyrite and bornite are leached slowly, with poor result. The leach solution contains only 1–6 g/L of copper with impurity elements such as iron, aluminum, zinc, calcium, and magnesium; existing, solvent extraction is usually used to extract and enrich copper from the solution.

In addition, the process can be used to extract copper in situ. That is, without removing the material from the waste pile or from the ground. The net result of the use of this process is that copper can be produced from sources that in the past would have gone untouched, thus reducing the reliance on conventional ore bodies.
