| 摘 要： | 采用富氧底吹“三连炉”造锍捕金工艺处理高砷锑复杂难处理金精矿,实现多金属高效回收。针对复杂金精矿火法处理工艺中金属收得率和工艺调控需求,结合生产实践总结了多种杂质元素分配行为与规律,优化了配矿中不同杂质元素含量,并对不同复杂金精矿在熔炼过程中的铜锍品位进行有针对性的调控,即高砷物料铜锍品位控制在65%,高铅物料铜锍品位控制在72%。可实现复杂难处理金精矿三连炉熔炼中铅、锌、砷、锑、铋、镍整体脱除率达98%以上,为黄金行业绿色冶炼及可持续发展提供参考。

| Abstract: | Refractory gold concentrate with high arsenic and antimony bearing was treated by oxygen enrichment bottom blowing gold-catching process in "triple consecutive furnace" to efficiently recover valuable metals. Distribution behavior and law of various impurity elements were summarized according to requirement of metal recovery rate and process control in pyrometallurgical process. Content of different impurity elements in ore blending was optimized, and grade of matte for different refractory gold concentrates was determined, in which the grade of matte in high arsenic ores was controlled at 65%, and the grade of matte in high lead ores was controlled at 72%. The overall removal rate of lead, zinc, arsenic, antimony, bismuth and nickel in refractory gold concentrate can reach 98% above. It can provide reference for green smelting and sustainable development of gold industry. |
