Harmless resource utilization method for dump leaching tailings in gold industry
The invention belongs to the technical field of harmless resource utilization of dump leaching tailings, and particularly relates to a harmless resource utilization method of dump leaching tailings in the gold industry. The technology of hydrogen peroxide/biological leaching, reselection, ozone treatment, screening, reselection, concentration and filter pressing and activated carbon catalytic oxidation is adopted, and harmless comprehensive recovery of gold concentrate and gravel aggregate from heap leaching tailings in the gold industry is achieved. The method is simple in process, good in treatment effect, high in treatment efficiency, stable and reliable in operation, low in operation cost, high in benefit and high in comprehensive utilization rate of tailings, and the problem that heap leaching tailings are difficult to treat and dispose in the gold mine is solved in multiple aspects.
本发明属于堆浸尾渣无害化资源化技术领域，特别涉及一种黄金行业堆浸尾渣无害化资源化利用方法；采用双氧水/生物淋洗‑重选‑臭氧处理‑筛分‑重选‑浓缩压滤‑活性炭催化氧化的工艺，实现了黄金行业堆浸尾渣无害化综合回收金精矿与砂石骨料，本发明流程简单、处理效果好、处理效率高、运行稳定可靠、运行成本低且收益高、尾矿综合利用率高，多方面解决了黄金矿山面临的堆浸尾矿处理处置难的问题。
