摘要
本文基于紫金铜业稀贵厂的工艺实践,分析了铜阳极泥预处理工艺存在的主要问题,并介绍了相应的改进措施和取得的成效。通过工艺设备优化和改进,70%以上的硫酸钡可在预处理阶段脱除,铜阳极泥铜含量可降至0.6%以下,并大幅减少金银损失,保证了后续卡尔多炉系统稳定顺畅运行。
Based on the practice in rare and expensive metal plant of Zijin Copper Co.Ltd,the paper analyzes the main problems existing in the pretreatment process of copper anode slime,and introduces corresponding improvement measures and achievements.Through optimization and improvement of process equipment,more than 70%barium sulfate can be removed in the pretreatment stage,with copper content in copper anode slime reduced below 0.6%.Also,the loss of gold and silver is significantly reduced.These measures ensure the smooth and stable operation of the follow-up Kaldo furnace system.
