Life Cycle Assessment (LCA) of Environmental Impact of Copper Slag Recycle Process

摘要：

The life cycle assessment method is applied to investigate the environmental impacts of copper-slag and copper-ore concentration process.Some environmental load data of copper production are obtained.The result indicates that damage level of human health,ecosystem quality and resources respectively is 0.174,0.0203,0.246 in the copper-slag concentration and 0.112,0.0136,0.299 in the copper-ore concentration.Environmental impact of copper-slag production (0.44) is more than that of copper-ore production (0.42),but can meet the environmental protect demand.With domestic copper concentrate supply gap enlarging,recovering copper from slag will lead to a significant improving of resource utilization and development of circulation economics.
