中国是世界铜的第四大生产国和第三大消费国。国内提炼铜的主要原料是铜精矿。据文献 [1 ]介绍 ,当铜精矿中镍的含量在 0 .1 %以上时 ,就影响电解铜的质量。优质的电解铜中镍含量在 w Ni0 .0 0 1 %以下 ,而高纯阴极铜中则要求锡、镍、硅、锌、钴等杂质总量不大于 w总 0 .0 0 0 China is the fourth largest producer of copper and the third largest consumer of copper in the world. Domestic refined copper is the main raw material of copper concentrate. According to the literature [1], when the content of nickel in copper concentrate is above 0.1%, the quality of electrolytic copper is affected. The quality of electrolytic copper in the nickel content of w Ni0. 0 0 1%, while the high-purity cathode copper is required tin, nickel, silicon, zinc, cobalt and other impurities is not greater than the total w 0. 0 0 0
