The new allocation method of environmental load about process of the coproduction by reaction heat of metallurgy and the comparisonof the allocation method by mass of materials were presented. The results indicated that environmental loadof nickelwere more than that of copper, and the allocation method was more reasonable by reaction heat of metallurgy in the process of coproduction.
