Abstract:Copper is an important basic raw material for the development of national economy, and copper smelting industry, as a basic industry, occupies an important position in the national economy. With the proposal of "double carbon" goal and the deepening of the concepts of "double cycle" and "green development", the copper smelting industry is facing huge challenges and opportunities. The key to the development of new productivity in traditional industries lies in combining scientific and technological innovation and industrial innovation, so as to promote the upgrading and transformation of traditional industries. Based on the status quo of copper smelting industry, focusing on the path and method of realizing the dual-carbon goal of copper smelting industry, combined with the status quo and trend of technological development of the industry, the application and key development of advanced low-carbon technology in copper industry were proposed. Taking a copper company in Fujian as an example, the transformation and upgrading of the industry and the layout of production capacity were discussed. Finally, the implementation of measures for the company""s low-carbon development, and the new concept for copper smelting technology in low-carbon environmental protection and green development, as well as in the future development trend of the application and progress were constructed. It aims to guide the copper smelting industry to develop in a more environmentally friendly, efficient and sustainable direction, and provide support for the low-carbon and green development of copper metal.
