FIELD: metallurgy; production of high purity metals. SUBSTANCE: process is carried out at temperatures within 400 and 850 C. Cathode current density is maintained within 0.1 and 1.0 A/cm, and anode current density should be 10 to 100 times lower. EFFECT: production of high purity scandium by electrolysis in medium of melted halide salts containing scandium trichloride or trifluoride. |
