Platinum have become a metal, which is today necessary for every new car production due to its catalytic role, mainly reduction of toxic gases. Prices and demand for platinum are shown as well as the possibilities of recovery this metal from secondary materials, especially spent auto catalyst. Paper presents the short review of platinum production from primary materials – the kind of ores, places where platinum is mined. However, resources of primary platinum are limited and quickly depleted. Platinum is also received from by-product obtained from the treatment process of other metals such as copper or nickel and these methods are also shortly shown. Finally, to meet the future demand and protect the platinum resources the hydrometallurgical, pyrometallurgical and even biometallurgical processes of platinum recovery from different waste e.g. electronic scrap, spent catalyst are counted and briefly characterized. The main focus was given on the spent auto catalyst – the general way of platinum recovery was given in more detail.Keywords: platinum, production, recovery, spent catalyst
