摘要
广东石铜阳极泥成分复杂 ,金银含量低 ,砷含量高 ,属难处理的物料 .采用酸浸和氨浸预处理 ,再氰化的方法 ,可有效地回收各有价金属 ,特别是金、银的回收率高 ,同时消除了砷对环境的污染 .试验指标如下 :氰化的浸出率为 Au 97% ,Ag 94 % ,回收率为 Au96 .6 % ,Ag 93.3% .该工艺流程简单 。
The copper anode mud in Guangdong Shilu, with a complicated composition, low contents of Au and Ag and high As content, is a difficult\|to\|tackle material. By the use of acid leaching and ammonia leaching pretreatment followed by cyanidation, valuable metals were effectively recovered from the anode mud, with high recoveries of Au and Ag, especially, and the environmental pollution caused by As in the anode mud was eliminated. For the test results, the cyanidation leaching rate of Au and Ag was 97% and 94%, respectively, the recovery of Au and Ag was 96\^6% and 93\^3%, respectively. The process has a simple flowsheet and good adaptability.
