摘　　要：铜阳极泥是资源综合回收的优选对象,分析各有价金属的分散情况对后续的回收有着指导性的方向作用。铜阳极泥选冶联合工艺较为成熟,具有不断外延拓展金属回收的空间。针对4000 t铜阳极泥物料的生产数据,考察了该工艺有价金属的走向,统计分析了金、银、硒、碲、铅、锑、铋、铜等在工艺流程中的分布率,摸清了有价金属主要分散情况。分析表明,金、银、硒、碲最大的分散点均为浮选尾矿,分别占分散总量的67%、37%、34%、58%,确定为重点管控对象。并结合统计分析结果对提高金、银、硒、碲回收率及铅、锑、铋、铜的回收提出了改进建议。Copper anode slime is an important resource for valuable metals,and the benefication-metallurgy is a conventional recovery process.The dispersions of various precious metals during the recovery process play a guiding role for the subsequent improvement on the process.Based on the relevant data from the recovery process of 4000 tons of copper anode slime,the distribution and dispersion profiles of precious metals during the recovery process were investigated.These metals include gold,silver,selenium,tellurium,lead,antimony,bismuth,copper,and etc.The results show that the largest dispersion points of gold,silver,selenium,and tellurium are all in the flotation tailings,accounting for 67%,37%,34%,and 58%of the total dispersion,respectively,and the flotation tailings were determined as a key control object.Based on the statistical analysis,some suggestion has been made in this paper for improving the recovery rates of gold,silver,selenium and tellurium,as well as the recovery of lead,antimony,bismuth,and copper.
