Platinum is produced in mines, especially in South Africa (lien Pretoria) Russia and Zimbabwe where it is found in relative high concentration around 5ppm<ref>Bau and al., 2015 http://dx.doi.org.gate1.inist.fr/10.1016/j.hydromet.2015.01.002</ref>. These absolute concentrations are rather lower than most of metal, so platinum in often a by-product of another mined resource as nickel or coal. |
Actually its extraction is realized by leaching the ore with chemicals (Clhorhydric acid, Aqua regia). This leaching can be supplemented with bioleaching. | Actually its extraction is realized by leaching the ore with chemicals (Clhorhydric acid, Aqua regia).
