METHOD OF ELECTROCHEMICAL PROCESSING REFRACTORY NICKEL ALLOY WASTES BEARING RHENIUM, TUNGSTEN, TANTALUM AND OTHER VALUABLE METALS |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: proposed method comprises anodic oxidation of melt in acid electrolyte at application of electric current. Note here that said anodic oxidation is carried out in acid electrolyte containing 150 g/l of HSO+50 g/l HCl. Applied direct electric current features density of 250-300 mA/cm. Application of said current is conducted at 20-40°C.EFFECT: notable increase in anodic oxidation rate.3 tbl, 2 ex |
