LCA study on electrolytic Nickel and Copper produced by coexistence ore
共生矿石生产电解镍/铜的生命周期评价研究

The environmental impacts of electrolytic nickel and copper produced by nickel-copper coexistence ore were investigated by the life cycle assessment. Some environmental load datum of copper and nickel was obtained. The new allocation method of environmental load about process of the co-production by reaction heat of metallurgy and the comparison of the allocation method by mass of materials were presented. The results indicated that environmental load of nickel were more than that of copper, and the allocation method was more reasonable by reaction heat of metallurgy in the process of co-production.
