铜阳极泥处理过程中碲锑铋砷的物质流分析研究
Substance flow Analysis of Tellurium、 Antimony 、Bismuth、Arsenic in the Treatment Process of Copper Anode Slime
本文对典型的铜阳极泥处理过程中碲、锑、铋、砷等元素的走向进行分析研究，旨在明晰其流向以及回收利用状况，通过优化现有的工艺方法，为实现高效综合回收利用铜阳极泥中这些元素提供指导。结果表明：在整个阳极泥处理工序中，碲比较分散，沉氯化银后液、分银渣、铂钯精矿、析铂钯后液中分别有20%、36%、30%、13%左右的碲；将近90%的锑都存在于分银渣中，少量分散在沉氯化银后液中；铋分散在分银渣、铂钯精矿、沉氯化银后液以及粗银粉中，它们分别占38%、 24%、 29%、9%左右；砷分散比较严重，主要存在于沉氯化银后液、分银渣、析铂钯后液中，分别占39%，47%，4%，其他地方只有少部分。
his paper has studied the substance flow analysis of tellurium, antimony, bismuth, arsenic in a typical copper anode slime treatment process, in order to explain the situation of the flow & recycling and recovery methods of these metals, and provide guidance for the high-comprehensive utility of these metals in copper anode slime. The results showed that: in the anode slime treatment processes, the tellurium is scattered in the liquid after precipitated silver chloride(20%)、silver separating residue(36%)、Pt-Pd Concentrate(30%) and the liquid after precipitated Pt-Pd Concentrate(13%). Nearly 90% of antimony is found in silver separating residue, only a small part scattered in the liquid after precipitated silver chloride. Bismuth is distributed in silver separating residue (38%)、 Pt-Pd Concentrate(24%)、the liquid after precipitated silver chloride(29%) and Crude silver powder(9%). Arsenic is dispersed more seriously, mainly in the liquid after precipitated silver chloride (39%)、silver separating residue(47%) and the liquid after precipitated Pt-Pd Concentrate(4%).
