有色金属是应用广泛的重要原材料,我国经济的持续发展,使国内市场对有色金属的需求大幅度增加。随着需求的持续增长,我国有色金属资源与需求之间的矛盾日益突出。因此,为了保证国家有色金属资源的供应安全,必须保持国有经济在有色金属工业中占有一定地位。 Non-ferrous metal is an important raw material with a wide range of applications. The sustained economic development in our country has greatly increased the demand for non-ferrous metals in the domestic market. With the continuous growth of demand, the contradiction between non-ferrous metal resources and demand in our country has become increasingly prominent. Therefore, in order to ensure the supply of national non-ferrous metals resources, the state-owned economy must occupy a certain position in the nonferrous metal industry.
