The use of composite calcined pellets obtained according to a sequential scheme of chemical and gravitational beneficiation of dump sludge tailings of the Dubersay tailing dump as a part of a charge with factory chromium concentrate enabled to obtain high-carbon ferrochrome FeCr70C90Si4LP China Standard where the low phospho-rus content is not more than 0,03 % and that of sulfur is not more than 0,1 %. The obtained samples of high-carbon ferrochrome and slag were studied. The maximum chromium content was 57,14 % at 1 750 °C, the charge sample included 50 % of experimental pellets and 50 % of factory concentrate and reducing agent 17 %, chromium recovery into the alloy was 80 %.
