| 摘 要： | 运用生命周期评价(life cycle assessment,LCA)方法,对用火法、湿法两种方法生产金属铜过程的环境协调性进行了研究,得到了铜生产过程中各工序的环境负荷数据.评价结果表明,铜冶炼的环境影响与生产工艺相关.湿法炼铜的能耗、温室效应、酸化效应,人体毒害分别只有火法炼铜的43.2%、45.2%、5.1%和5.0%.湿法冶炼铜过程环境影响明显低于火法炼铜的环境影响.

| Abstract: | The life cycle assessment method was used to investigate the environmental impacts of metallic copper production with hydrometallurgical and pyrometallurgical processes.Some environmental load datum of copper in the production were obtained.The results indicate that environmental impacts of copper are related to metallurgical technology.The energy consumption,greenhouse effect,acidification and human toxicity of copper in the pyrometallurgical processes only is 43.2%,45.2%,5.1% and 5.0% of those of copper in the pyrometallurgical processes.Environmental impact of copper production with hydrometallurgy is less than that of pyrometallurgical. |
