矿产资源利用的循环经济分析

Analysis on Recycling Economy in Exploiting and Utilizing Mineral Resources

矿产资源是不可再生资源,我国人均资源占有量相对偏少。为了建设资源节约、环境友好型社会,必须大力发展循环经济。江西铜业公司坚持制度创新和技术创新,大力发展循环经济,在铜矿采掘、分洗和铜冶炼等各个环节,把生产中的废弃物加工成有市场需求的产品,使资源得到充分利用,能量有效地转换,取得了显著的经济、社会和生态环境效益。案例研究的结果表明,发展循环经济,企业必须树立建设节约型社会的使命感和责任心,遵循市场规律,大力开展科技创新,研究开发废弃物再利用的关键技术,尽可能将污染物在企业内部转变为产品,形成循环经济产品链或产品网,提高经济效益。政府要创新机制,完善政策、健全法制、加强宏观管理,营造发展循环经济的良好制度框架和政策环境。

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 ×10^6t of H2SO4,1 × 10^8kW.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 3×10^9 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.
