METHOD OF PRODUCING NICKEL ANODES FOR ELECTROLYTIC PRODUCTION OF NICKEL Russian patent published in 2001 - IPC

Abstract RU 2166554 C1

FIELD: nonferrous metallurgy; applicable in production of nickel anodes by smelting powder of reduced nickel protoxide from cinder of roasting of nickel concentrate obtained by flotation separation of copper-nickel converter matte. SUBSTANCE: method includes reduction of nickel protoxide with production of powder of crude nickel which is further subjected to treatment in presence of reducing agent by electric arc smelting of crude nickel powder with bulk density of not less than 2.7 t/cu.m, degree of metallization is at least 90% and specific power consumption, 950-1050 kWh/t. EFFECT: higher productivity of melting furnace, reduced consumption of electrodes and decreased heat power intensity. 1 ex
