Technology of the Conversion of the Departure to Zinc Industry with Reception of Ferro-Alloy and Pairs Non-Ferrous Metal

Abstract

The paper considers a possibility of using zinc production wastes as secondary metallurgical raw material that can be complexly converted to commercial products (a ferroalloy and collective sublimates of the non-ferrous metals). Industrial tests yielded a degree of transition of Si in ferroalloy up to 96%, Fe up to 97%, and degree of extraction of Zn in sublimates of 99,6%, Pb of 99%. The RRC-16.5 electric furnace is recommended as the main unit for electrothermal melting zinc production wastes to obtain a ferroalloy and non-ferrous metal sublimates.
