摘　　要：铁矿石采选过程是重要的能源消费源和温室气体排放源,为更好的推进铁矿石采选业的温室气体减排,需要采用全生命周期方法对铁矿石采选过程中的直接和间接温室气体排放进行详细计算。为避免传统的过程生命周期评价方法在计算过程中产生的截断误差,本文基于投入产出全生命周期评价方法(EIO LCA)对铁矿石采选全生命周期的能源消费和温室气体排放进行了计算。计算结果显示,最终获取1t铁矿石的能源消费强度为0.089tce;温室气体排放强度为2.138tCO2-eq,主要源于煤炭,约占总排放量的48.1%。The mining and processing of iron ore is an important source of energy consumption and greenhouse gas emission. In order to reduce the mining and processing of iron ore greenhouse gas emission, the direct and indirect emissions of greenhouse gas should be calculated based on life cycte method. In order to avoid the truncation error produced by the process-based life cycle assessment method, the economic input-output life cycle assessment method has been used to calculate the life cycle energy consumption and greenhouse gas emissions from mining and processing of iron ores in this article. The calculation results show that the energy consumption intensity is 0.089 tce, and the greenhouse gas emission intensity is 2. 138 tCO2-eq. The coal is the main source of greenhouse gas emissions, which is accounting for about 48.1% of total emissions.
