基于新型捕收剂ZY-202的某铜钼分离工艺优化试验研究

Experimental Study on Optimization of a Cu-Mo Separation Process Based on the Novel Collector ZY-202

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。

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.
