| + | Nowadays, the platinum is drawn along a linear pathway. Platinum is produced in mines, especially in South Africa (lien [[Team:Pretoria_UP|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. | ||

| + | The process we’ve designed allow to shape the economy in a circular way. Instead of being wasted in environment, platinum is re injected in economy. | ||
