摘要
高技术金属资源已成为国家战略性新兴产业发展不可或缺的关键原材料,而废旧电脑中含有种类丰富的高技术金属资源,具备广泛的开发利用前景。随着社会经济发展和人民生活水平提高,我国电脑普及率逐年提升,并已成为全球最大的电脑生产国和消费国,每年报废大量废旧电脑。因此,本文在区分台式电脑和笔记本电脑的基础上,运用动态物质流方法对我国不同类别电脑报废量及蓄积其中的各类高技术金属社会存量进行估算,并讨论回收方式对回收效率的影响。研究结果表明:①2010—2019年期间,我国电脑报废总量超过14亿台;②2010—2019年期间,我国废旧电脑中蓄积的各类高技术金属总社会存量超过4600 t;③随着回收方式的转变和回收效率的提升,未来蓄积在废旧电脑中的各类高技术金属资源将成为国家战略性关键矿产的重要来源。本文为科学合理开发我国废旧电脑中蓄积的各类高技术金属资源提出合理性建议,并展望未来研究方向。
High-tech mineral resources have become the indispensable key raw materials for the development of national strategic emerging industries.There are many kinds of high-tech mineral resources in waste computers,which have a wide development and utilization prospect.With the development of the social economy and the improvement of people's living standard,China has become the world's largest computer production and consumer country,with a large number of scrap computers every year.Therefore,in this paper,on the basis of differentiating the desktop computer and the notebook computer,dynamic material flow method is used to estimate the scrap volume of different types of computers and the social stock of high-tech minerals in China.The influence of recycling methods on recycling efficiency is discussed.The research results show that China's total number of computer scrap is more than 1.4 billion from 2010 to 2019.From 2010 to 2019,the total social stock of all kinds of high-tech minerals accumulated in waste computers in China exceeds 4600 t.With the transformation of the recycling methods and the improvement of recycling efficiency,all kinds of high-tech mineral resources accumulated in waste computers will become an important source of national strategic key minerals in the future.This paper puts forward some reasonable suggestions for the scientific and rational development of various kinds of high-tech mineral resources accumulated in waste computers in China,and looks forward to the future research direction.
