NICKEL DEFICIENCY MAKING UP METHOD AT PROCESS OF NICKEL ELECTROLYTIC REFINING

摘要

FIELD: metallurgy, possibly processes related to electrolytic refining of nickel for making up its deficiency in solution, production of nickel salts. ^ SUBSTANCE: method comprises steps of preliminarily disintegrating scrap metallic nickel and cuttings of cathode nickel till size 5 - 20 mm; electrolytic dissolving of it by passing alternating current with current intensity 2500-20000 A/m2 in sulfur acid solution, 130 - 200 g/l. ^ EFFECT: short time periods for preparing additional volumes of solution used for nickel refining. ^ 1 tbl, 12 ex
