Abstract: The minerals are nonrenewable resources.For building a resources-saving and environment friendly society,recycling economy should be developed.The material is fully utilized in multiple hierarchies;energy is effectively converted through development of recycling economy in the technological process on mining,mineral separation and copper smelting in Jiangxi Smelting Copper Corporation.About 43500t of copper,12t of gold,300t of silver,1.1×106t of H2SO4,1×108kW·h of the electric energy and rhenium,molybdenum,selenium etc were produced by use of waste and 85% of waste water was repeatedly used every year.The profit from recycling economy amounts to 3×109 yuan and accounts for 24.6% of the total profit of the company in 2004.The dramatic economic,social and ecological benefits have been achieved simultaneously.The result of the case study shows that,the enterprises should enhance responsibility on building a resources-saving society,should promote and strengthen product chain or product network of recycling economy by advocating science & technology innovation and exploiting the key technology of reuse of the wastes and converting them into demanded products,in order to develop recycling economy for achieving most economic benefits with least resource expenditure and environmental pollution.The governments should set up the new mechanism,perfect the legal system and enhance the management in order to develop recycling economy.

Key words: recycling economy, exploiting waste to products, technology innovation
