| Abstract: | The method of copper determination in copper matte was established based on copper composition and structure characteristics. The course of pretreatment by mixed acid and sample titration were discussed mainly. The determination scope of copper was 4.80%~32.00%. The recovery value was 97.70%~101.26%. The precision that is standard deviation was 0.026 %~0.10%. The method was favorable in solving the difficulty of determining copper in copper matte. |
