Prediction and potential analysis of green metallurgy innovation development situation

Fifth, the circular economy industrial innovation project. Establish new theories and methods for green extraction of complex mineral resources and recycling of secondary resources, and drive the upgrading of efficient utilization of resources. Guide the construction of intra-industry/cross-industry resource and energy links, optimize the allocation, supply and disposal of resource and energy utilization, and establish a regional multi-industry cycle model. The key research contents include: (1) Constructing the circular economic ecological chain of coke oven gas scale hydrogen production and petrochemical industry; (2) Establish a green process for the comprehensive and efficient utilization of oil, coal and natural gas resources to produce clean products, and form a complete set of technologies for coal gasification combined cycle polygeneration of chemicals; ③ Promote non-ferrous metals "raw material production + terminal application" connection development mode, through the upstream and downstream linkage to achieve high value-added utilization of resources, promote product consumption upgrade, promote "aluminum to save wood", "aluminum instead of steel", "aluminum instead of plastic" and so on; ④ Construction of "aluminum profiles - auto parts - building components - household products", "rare earth metals - new energy materials - new energy auto parts - power battery materials" and other industrial clusters; (5) Promote the integrated development path of mining, smelting and processing of the copper industry, support the integrated development of the aluminum industry with coal, electricity, chemical industry and clean energy, and form a number of distinctive industrial clusters.

The sixth is the non-ferrous and steel industry link innovation project. Strengthen the support for the green cycle of resources in the metallurgical industry, and break through key technologies such as the recovery of valuable elements of secondary materials and the recycling of associated metal solid waste. The key directions involve metal separation and resource extraction in ferrous and zinc-containing solid waste in the whole process of nonferrous and iron and steel, and multi-metal collaborative smelting in the process of nonferrous and iron and steel metallurgy, so as to reduce the dependence on mineral resources and improve the recovery rate of secondary and rare resources. We will carry out cross-industry and cross-departmental innovation industry chain projects, implement industrial chain coordination between mining and metallurgy, housing construction, transportation, environmental protection, and the environment, and promote the consumption of solid waste resources.
