摘要
基于多金属回收车间选别作业中金属资源的高效分离回收,开发了一种新型的硫化矿捕收剂ZY-202,并对现有的浮选工艺以及药剂制度进行了改良.与现有的浮选工艺相比,将钼粗选阶段使用的药剂由煤油+2#油替换为煤油+ZY-202,并且对粗选精矿连续进行2次精选得到钼精矿.在选铜过程中,将粗选阶段的捕收剂替换为ZY-202+TL-1,同时在粗选以及扫选过程中不再使用硫酸锌和亚硫酸锌作为抑制剂,对粗选得到的精矿继续进行2次精选后得到最终的铜精矿.基于优化后的药剂制度与浮选流程进行闭路试验后,得到的钼精矿Mo品位与回收率分别为 52.43%和96.70%,铜精矿Cu品位与回收率分别为25.57%和92.26%;Zn的损耗率由原来的63.07%降低至13.68%.ZY-202是铜钼分离过程中一种高效的捕收剂,对简化选矿流程,降低企业的生产成本具有重要意义.
Abstract
Based on the efficient separation and recovery of metal resources in the separation opera-tion of multi-metal recovery workshop,a new sulfide ore collector ZY-202 is developed,and the existing flotation process and reagent system are improved.Compared with the existing flotation process,the reagent used in the molybdenum roughing stage is replaced by kerosene+2#oil with kerosene+ZY-202,and the rough concentrate is endured two stage cleaning to obtain the molybdenum concentrate.In the process of cop-per separation,the collector in the roughing stage is replaced by ZY-202+TL-1,and zinc sulfate and zinc sulfite were no longer used as inhibitors in the roughing and scavenging processes.The final copper concen-trate is obtained after two stage cleaning on the rough concentrate.After closed-circuit test based on the opti-mized reagent system and flotation process,the Mo grade and recovery of molybdenum concentrate is 52.43%and 96.70%,respectively,and the Cu grade and recovery of copper concentrate is 25.57%and 92.26%,respectively.The loss rate of Zn decreases from 63.07%to 13.68%.ZY-202 is an efficient collec-tor in the process of copper and molybdenum separation,which is of great significance to simplify the benefi-ciation process and reduce the production cost of enterprises.
