| Abstract: |
| An iodometric titration approach was established for determination of copper in copper matte based on the composition and structure characteristics of copper matte. The focus of this paper is to investigate the sample pretreatment of dissolving copper matte sample with mixed acid and the titration procedures. Using the developed approach, the concentration range of copper that can be determined was from 4.80% to 32.00% with the relative standard deviations of 0.24 % -0.53%. The copper recoveries were from 97.70% to 101.26%. This study solved the problems in the determination of copper content in copper matte. |
