- 中文摘要: 本文研究應用汞齊精鍊電解法,由含不純物金屬較多的氧化鋅提煉純鋅金屬。氧化鋅以酸溶解後以簡單的PH調整和鋅粉處理,然後此溶液以汞齊精鍊電解法提煉純鋅金屬。適當地調整汞齊陽極電位則可阻止不純物溶入電解液中,而殘留在汞齊中,以此精鍊法可獲得99.99%以上的鋅金屬
- 英文摘要: The application of amalgam electrolysis to the recovery of zinc from highlycontaminated zinc oxide were studied. After removal of some impurities by simpletreatment of PH adjustment and zinc dust treatment, this solution was used toproduce high-purity zinc metal by amalgam electrolysis. By proper adjustment ofamalgam anode electrode potential, impurities were prevented to dissolve to elect-rolyte. 99.99% zinc metal could be produed by this method.
