Abstract: Copper is one of the earliest ancient metals discovered by human beings, and it is also an important strategic metal mineral in China.In the case of the serious shortage of non-ferrous metal resources in China, recycled copper has alleviated the serious shortage of copper resources in China to a great extent and broadened the source channels of copper.Through on-site investigation and enterprise information understanding of nine recycled copper enterprises in Sichuan province, this paper studies material flow analysis of flow, flow direction, and reproduction of the copper industry.This paper also shows assessment of socio-economic value and ecological environmental value of metal copper recycling.The results show that recycled copper could save 18.16% of energy on average compared to smelted copper, the recycling and reusing of waste copper could lead to positive results in terms of energy conservation, consumption reduction, shortening of production process cycles, environmental protection, and improvement of ecological and environment value.Sangkey diagram of annual output of recycled copper of key metal copper enterprises in Sichuan province is also performed, and suggestions are given from ecological, policy and economic aspects.
