摘　　要：基于LCA生命周期法与IPCC因子法,提出适用于铜冶炼企业的产品碳足迹核算方法。以贵溪冶炼厂为模版,以矿铜冶炼全流程以及杂铜冶炼短流程为核算对象,以各生产工序为核算单元,对铜冶炼全流程碳足迹进行了核算。分析表明,矿铜冶炼工艺购入电力碳足迹占比高达86.64%,回收铜冶炼工艺购入电力碳足迹占比达53.8%,是铜冶炼产品碳足迹的主要贡献者。基于碳足迹核算结果,提出了铜冶炼企业减排环节与优化路径。Based on LCA life cycle method and IPCC factor method,an accounting method for product carbon footprint of copper smelting enterprises is proposed.Taking Guixi Smelter as the template,the whole process of copper smelting and the short process of miscellaneous copper smelting as the accounting object,and each production process as the accounting unit,the carbon footprint of the whole process of copper smelting is calculated.The analysis result shows that the carbon footprint of purchased electricity from copper smelting process accounts for 86.64%,and the carbon footprint of purchased electricity from recycled copper smelting process accounts for 53.8%,which is the main contributor to the carbon footprint of copper smelting products.Based on the results of carbon footprint calculation,this paper puts forward the emission reduction link and optimization path of copper smelting enterprises.
