Nowadays, the platinum is drawn along a linear pathway. Platinum is produced in mines, especially in South Africa (lien Pretoria) Russia and Zimbabwe where it is found in relative high concentration around 5ppm (Bau and Al., 2015). 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.
