Abstract Paper shows that at pulp processing (NH4)2PtCl6 by monoxide of carbon at atmospheric pressure and t = 20–90 °C there is a clearing of impurity of a palladium and rare platinoids, and platinum can be received by hydrometallurgical method. Allocation of iridium in the form of an individual product — carbonylchloride from which it is possible to receive a powder of iridium of high cleanliness can be realized by the similar method from mix (NH4)2PtCl6 + (NH4)2IrCl6, polluted by others platinum and nonferrous metals.
keywords Platinum metals, chloride complexes, monoxide of carbon, hydrocarbonylchloration, clearing, concentration, extraction, allocating.
