Technology of the conversion of the departure to zinc industry with reception of ferro-alloy and pairs non-ferrous metal

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.
