金隆铜业公司阴极铜杂质分布的调查

INVESTIGATION ON IMPURITY DISTRIBUTION IN CATHODE COPPER OF JINLONG COMPANY

为进一步提高金隆铜业有限公司阴极铜的质量，确保1999年在LME注册成功，按照GB/T467－1997标准中Cu－CATH－1要求[1]，用ICP－AES、GFAAS分析法，调查了阴极铜中杂质分布，同时进行了一系列验证性试验．本文叙述了调查方案、调查结果、结果分析及杂质产生不均匀分布的原因，从而为稳定阴极铜质量提出了改进方向。

For improving the quality of cathode copper of Jinlong Co. and insuringsuccessful registration in LME in 1999, we have investigated impurity distribotion in cath-ode copper according to the requirement of Cu-CATH-1 of GB/T467-1997 and in theways of ICP-AES and GFAAS. At the same time, we have carried out experimentalverification.This paper describes scheme and result of the investigation as well as resultanalysis and the reasons for uneven impurity distribution. Therefore, the improving direc-tion of stabling the quality of cathode copper is put forward.
