METHOD OF WINNING OF METAL COPPER FROM COPPER SULFIDE |
| 摘要 |
FIELD: nonferrous metallurgy. SUBSTANCE: cadmium oxide in amount of 2-6 % is dissolved in melt and process is carried out at cathode current density equal to 0.2-1.5 A/cmand anode current density of 0.25-1.9 A/cm. Use is made of indifferent anode and liquid or indifferent solid cathode at interpole distance of 2-5 cm. EFFECT: increased capacity, cut down capital outlays, enhanced ecological situation at electrolysis of alkaline-carbonate melt. |
