降低采选过程中有用矿物的损失,是保证提高采掘工业的经济效益、合理利用矿物原料资源的主要方向之一。七十年代,采取了一系列降低矿物损失的措施,特别是采矿过程中采取了降低有用矿物损失的实际措施。国民经济计划规定了回收采选过程中有用矿物的任务,确立了保护地下资源的方法,贯彻了计算采矿过程中矿物损失的规范性文件,采用了全国统一的矿物损失报表等等。
Reducing the loss of useful minerals in the process of mining and dressing is one of the main directions to ensure the economic benefits of the extractive industries and to make rational use of mineral raw materials. In the 1970s, a series of measures were taken to reduce mineral losses. In particular, practical measures to reduce the loss of useful minerals were taken during the mining process. The national economic plan stipulates the task of recovering useful minerals during the mining and dressing process, establishes the method of protecting the underground resources, implements the normative documents for calculating the mineral loss in the mining process, adopts the unified national mineral loss report and so on.
