| Abstract: |
| In recent years, mining and smelting in China have brought serious pollution to the surrounding ecological environment. As an important environmental management tool, LCA is of great significance for improving the production process of products, reducing environmental pollution, and carrying out environmental, product and process coordination. Through extensive research on G company and the life cycle assessment method, this paper analyzes the environmental impact of the wet smelting and separation product (REO) produced by the company. The non-renewable fossil energy ADP, global warming potential GWP, acidification effect AP, photochemical effect POCP, human health hazard HT environmental impact type were selected as the main environmental impact types of G company wet smelting and separation product life cycle. The contribution of each production process to the type of environmental impact is compared, and the company should focus on optimizing the burning process stage in the production process to control the SO2 emissions during the production process. |
