The production of nonferrous metals includes geological exploration, mining, processing, smelting and processing. With the development of science and technology, advanced technology of physics and chemistry is constantly applied to the innovation of non-ferrous metal metallurgy technology, which makes the non-ferrous metallurgy technology make new progress. Pyrometallurgy has been gradually eliminated due to its own shortcomings

At present, most non-ferrous metallurgical enterprises and research teams mainly focus on hydrometallurgy and electrometallurgy for production and research. The continuous innovation of non-ferrous metallurgy technology is facing many challenges. It is developing in the direction of green environmental protection, utilization of marine resources and development of metal substitutes.

However, the contradiction between industrial development and environmental protection, the difficulty of marine resources utilization technology, the high cost of metal substitutes research and development and production have not been effectively solved. Considering many factors, compared with the above research direction, the research prospect of secondary resource recycling and reuse is relatively broad; if the research and development results of early laboratory are applied to the later production line, it will be another major breakthrough in non-ferrous metallurgy technology.
