云南某高硫铅锌选矿厂自投料试车以来,生产指标稳步提升,但原矿品位的增加、矿石性质改变,给生产操作和管理带来了诸多问题,导致生产指标异常波动。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%,为企业创造出良好的经济效益。 Since a high-sulfur lead-zinc concentrator was put into operation in a high-sulfur lead-zinc concentrator in Yunnan Province, the production index has steadily risen. However, the increase of ore grade and the change of ore properties have brought many problems to production operation and management, leading to abnormal fluctuations of production indexes. Under the original technological process, the abnormal fluctuations of beneficiation indexes were gradually reversed by optimizing the technical measures of ore blending, improving the quality of grinding and grading products, optimizing the pharmaceutical system and optimizing the process of the process. The recovery rate of lead beneficiation increased by 0.65% and the zinc recovery rate Improve 0.43%, create a good economic benefits for the enterprise.
