摘要:

随着工业化进程加快,金属资源的关键性已成为我国乃至全球关注的问题,金属资源的大范围应用使其在生产时造成的环境影响越来越严重。为选择对环境影响较小的金属种类及生产方式,针对62种典型金属工业生产过程,对其相关的环境影响评价研究进展进行总结,重点关注黑色金属和有色轻、重金属生产过程的环境影响,并对与碳足迹分析相关的研究进行重点总结评述。重金属在生态毒性、人类健康等毒性影响方面均有较大影响;稀有金属和准金属的相关评价主要集中在Li和V上,且是未来的主要研究方向;贵金属相比其他金属造成的碳排放较为显著。金属生产行业未来需重点考虑金属元素自身性质,依据其不同阶段的污染程度优化生产方式,且聚焦金属生产行业的温室气体排放问题。

Abstract:

With the acceleration of the industrialization, the criticality of metal resources has become a concern of China and even the world, and the large-scale use of metal resources makes its environmental impact more and more serious in production processes. Under dual-carbon goals, in order to select metal production processes with low environmental impact, this study focused on 62 typical metal industrial production processes, summarized the relevant environmental impact assessment studies, and related to carbon footprint analysis is summarized during metal production processes. The environmental impacts of ferrous metals as well as non-ferrous light and heavy metals production processes were focused on. In the production of ferrous metals, the environmental impact can be reduced by using biomass instead of fossil energy, choosing suitable Mn smelting methods and reducing the content of Cr6+ in nature. Non-ferrous light metals were currently produced in a large number of metals with diversified production methods, which had a greater impact on greenhouse gas emissions and ecological toxicity. Heavy metals have a great impact on toxic effects such as ecotoxicity and human health. The mining and refining process of precious metals will have a serious impact on the atmosphere and water, which should be paid attention to. There were few studies on the evaluation of rare metals and quasi-metals, which mainly focused on Li and V, however its importance is becoming more and more significant, and the development potential is huge. Compared with other metals, the carbon emissions caused by precious metals are more significant, and the five metals with the highest Global Warming Potential (GWP) are Rh, Pt, Au, Ir and Sc. This research can effectively solve the environmental problems of metal production while promoting industrial development through green and efficient metal production processes.
