在开采多金属矿石时,人们越来越注意工艺填图问题,特别是贫矿石、中等品位矿石和富矿石分别开采和加工可能性的评价问题。因为这几类矿石的结构和构造特点不同,在很多情况下有可能大大提高有用组分的回收率,降低最终产品的生产费用,改善矿产资源的综合利用。按照不同的开采费用,选取不同的采矿方法将矿床储量进行分类,也是采矿生产的紧迫任务。例如,用充填采矿法开采贫矿石和低价矿石显然是无利可图的。而且,多金属矿石包
In the exploitation of polymetallic ores, attention is being paid to the issue of process mapping, in particular the evaluation of the possibility of mining and processing, respectively, lean ores, medium grade ores and rich ores. Because of the different structural and structural characteristics of these types of ores, it is possible in many cases to greatly increase the recovery of useful components, reduce the production costs of the final product, and improve the comprehensive utilization of mineral resources. According to different mining costs, the selection of different mining methods to classify the deposit reserves is also an urgent task for mining production. For example, it is clearly unprofitable to exploit lean ore and low-cost ores by the Filling Mining Act. Moreover, multi-metal ore package
