中文摘要：

中国铜生产的环境负担被一条生命周期途径在典型技术，材料供应和环境排出物的上下文识别了并且确定。分别地，主要、第二等的铜生产使用铜矿石和碎片详细被分析。熔炼途径并且再循环铜碎片的闪光和洗澡作为代表性的铜生产过程被选择。定量分析也被进行在铜生产估计材料运输距离的影响。生命周期评价(LCA ) 结果证明那资源弄空和人的健康在中国铜生产显著地作出贡献到环境负担。另外，第二等的铜生产比主要生产有戏剧性地更低的环境负担。在在由闪光或洗澡熔炼途径的主要的铜生产的全面环境负担没有明显的区别。然而，资源弄空更低，人的健康的损坏为熔炼途径的闪光是更高的。生态系统优秀损坏为两条途径是细微的。从采矿阶段的环境负担在主要的铜生产在所有生命周期阶段贡献大多数。在第二等的铜生产，电解精制阶段统治。基于生命周期评价结果，为改进环境性能的一些建议被建议遇见中国铜工业的持续开发。

英文摘要：

The environmental burdens of Chinese copper production have been identified and quantified in the context of typical technologies, materials supplies and environmental emissions by a life cycle approach. Primary and secondary copper production using copper ores and scraps, respectively, were analyzed in detail. The flash and bath smelting approaches and the recycling of copper scraps were selected as representative copper production processes. A quantitative analysis was also conducted to assess the influence of material transport distance in copper production. Life cycle assessment （LCA） results showed that resources depletion and human health contribute significantly to environmental burdens in Chinese copper production. In addition, the secondary copper production has dramatically lower environmental burdens than the primary production. There is no obvious distinction in overall environmental burdens in primary copper production by flash or bath smelting approach. However, resources depletion is lower and the damage to human health is higher for flash smelting approach. Ecosystem quality damage is slight for both approaches. Environ- mental burdens from the mining stage contribute most in all life cycle stages in primary copper production. In secondary copper production, the electrolytic refining stage dominates. Based on the life cycle assessment results, some suggestions for improving environmental performance were proposed to meet the sustainable development of Chinese copper industry.
