发布时间:2018-12-20 07:38
【摘要】:云南某高硫铅锌选矿厂自投料试车以来,生产指标稳步提高,但原矿品位增加、矿石性质改变,给生产操作和管理带来了诸多问题,导致了生产指标的异常波动。在原有的工艺流程下,通过优化配矿技术措施、改善磨矿分级产品质量、优化药剂制度、流程局部优化等,逐步扭转了选矿指标的异常波动,铅选矿回收率提高0.65%、锌回收率提高0.43%,为企业创造了良好的经济效益。
[Abstract]:Since the trial run of high sulfur lead zinc concentrator in Yunnan Province, the production index has been improved steadily. However, the increase of ore grade and the change of ore properties have brought many problems to production operation and management, resulting in abnormal fluctuation of production index. Under the original technological process, by optimizing the technical measures of ore blending, improving the quality of grinding and classifying products, optimizing the pharmaceutical system, optimizing the local optimization of the process, the abnormal fluctuation of the mineral dressing indexes is gradually reversed, and the recovery rate of lead dressing increases by 0.65%. The recovery rate of zinc was increased by 0.43, which created good economic benefits for enterprises.
