Along with traditional raw materials (actually platinum and complex copper-nickel sulfide ores), technogenics waste of processing of polymetallic ores processing can be used as an alternative source for platinum group metals production. The largest technogenics platinum deposits are located in Russia. These deposits are presented by Norilsk technogenics deposits, and technogenics platinum-chromite scatters of Ural and Aldan. A major losses of platinum metals in “Norilsk Nickel” MMC (up to 20%) occurs due to the final shale formation during the concentration of basic copper-nickel materials. The total quantity of platinum group metals, coupled with final shale, is more then 5.5 g/t. Nickel-pyrrhotite concentrate, containing more than 10 g/t of platinum group metals, is formed after flotation concentration of pyrrhotite ores. Such concentrate can be a source for obtaining of rare platinoids, wich are only represented by the form of solid solutions in pyrrhotite and pentlandite. Previously, the of nickel-pyrrhotite concentrate processing was considered as unprofitable, because of low cost of platinum group metals, but the state of things has changed. Application of traditional methods for the stale pyrrhotite concentrates processing became complicated because of the presence of platinum group metals in the form of idusions in sulfide minerals, which makes the raw materials refractory. This article describes the most prospective Norilsk technogenics deposits:
— storages of magnetite concentrates (products of floatation concentration of rich chalcopyrite ores), which content in platinun group metals reaches 26 g/t);
— waste slags and dusts of systems of dry and wet gas purifications of metallurgical furnaces.
It should be noted that storage of dump concentration product and metallurgical productions is characterized by low orderliness of warehousing and mixing of different types of products. Another source of technogenics platinum deposits is platinumchromite scatters of Ural and Aldan, which are represent by the complex raw materials, containing different types of platinum group metals' minerals. The technogenic platinum deposits are varied by their nature, the content of metals, scales of accumulation and economic feasibility of processing.
