传统上采用的矿石开采和加工工艺包括:将采下的矿石提升到地表,运到通常距矿山几公里的选矿厂进行选矿。我们用采矿生产发展的历史观点来探讨所采用的工艺,这种生产的特点是:矿石中有用组分的品位不断降低;在矿山工程不断延深的条件下增加金属的产量,特别是增加采矿量。今后,这些趋势还会保持下去。 Traditionally used ore mining and processing techniques include lifting the mined ore to the surface and beneficiation at a beneficiation plant, usually a few kilometers from the mine. We use the historical point of view of the development of mining production to explore the process used, which is characterized by a continuously decreasing grade of useful constituents in the ore, an increase in the production of metals under deepening mining engineering, in particular the increase in mining the amount. In the future, these trends will continue.
