现代工、农业和科学技术的迅速发展,对有色金属的产量和质量提出了愈来愈高的要求。以铝、铜、铅、锌为例,1980年的全世界原生金属产量分别为1950年的11.3、2.8、2.1和2.9倍,根据预测,在2000年前对这些金属的需求量将以每年5.5%、3.8%、2.8%和2%的速率不断增长。这就要求有色冶金工业能处理各种复杂的甚至低品位的矿石原料、强化生产、降低能耗、控制污染以解决资源、产量、能源及环保等重大问题。因此,近年来有色冶金主要沿着提高过程适应性、强化、节能、综合利用和减少污染的
The rapid development of modern industry, agriculture and science and technology has set higher and higher requirements for the output and quality of nonferrous metals. Taking aluminum, copper, lead and zinc as examples, the worldwide primary metal production in 1980 was 11.3, 2.8, 2.1 and 2.9 times of that in 1950 respectively. It is estimated that the demand for these metals by 2000 will be 5.5 %, 3.8%, 2.8% and 2% of the rate of growth. This requires that the non-ferrous metallurgical industry can handle all kinds of complex or even low-grade ore raw materials, strengthen production, reduce energy consumption and control pollution to solve major problems of resources, output, energy and environmental protection. Therefore, in recent years, non-ferrous metallurgy mainly improves the process adaptability, enhance, save energy, comprehensive utilization and reduce pollution
