当前,从世界各国和国内来看,为了满足科学技术发展的需要,对有用金属的需要量将愈来愈大,不仅从地下开采出来的金属数量正在逐年增长,而且所采出的化学元素种类,也不断在增多。从目前开采地下有用矿床的发展趋向来看,主要有以下两个方面:一是不断增加地下有用矿床开采的深度;二是只能开采愈来愈贫的地下有用矿床。可是,在以

At present, from all over the world and from the domestic point of view, in order to meet the needs of the development of science and technology, the demand for useful metals will become larger and larger. Not only the amount of metals mined from the underground is increasing year by year, but also the types of chemical elements , But also constantly increasing. In view of the development trend of the useful underground deposits currently being exploited, there are mainly two aspects as follows: one is to continuously increase the depth of exploitation of underground useful deposits; the other is to exploit the increasingly poorer underground useful deposits. However, in order
