摘要
降低开采贫化率,减少矿石运输、提升和加工费用是矿山开采过程中的重要工作。里伍铜矿为了进一步提高选矿厂入选矿石品位,提高矿产资源的开发利用水平和效率,企业针对延伸工程矿石回采贫化率高的问题,采取了有效的技术、管理措施,降低了延伸工程采矿贫化率,为企业带来了较好的经济效益。
Reducing mining dilution rate and reducing ore transportation, promotion and processing cost are important work in mining process. Liwu copper deposit in order to further improve the concentrator ore grade, improve the level of development and utilization of mineral resources and the efficiency of the enterprise, to solve the problem of high extension engineering ore mining dilution rate, take technical measures effectively, reduce the extension project of the mining dilution rate, bring good economic benefits for the enterprise.
