Utilization of used automotive catalysts

Abstract

There were analyzed of available techniques for purposes of technology development and equipment design for used automotive catalysts (exhaust catalytic converter system) processing. These catalysts are contained precious metals. There was selected pyrometallurgical way of processing, and offered methods of overcoming known shortcomings of heat-resistant materials' direct melt. There was manufactured original complex on the ground of furnace with cold crucible (work space of 20 liters), ensuring continuous process of heat-resistant material's cumulative smelting. There were carrying out tests of complex, showed enabling extracting as much as 98 per cents of precious metals into alloy suitable for delivery on refinery. There were intended tracks of further improvements of process and equipment for solution of tasks' broad spectrum for processing of heat-resistant materials.
