Life Cycle Assessment (LCA) of Ore Transportation Route Alternatives for Eagle Mine

This research applies the Life Cycle Assessment (LCA) evaluation toward transportation options of existing mining operations in the Upper Peninsula of Michigan. More specifically, it performs a comparative life cycle assessment of three different route alternatives for transporting copper/nickel ore from Eagle mine to Humboldt mill to quantify the potential environmental impacts of the transportation activities in terms of greenhouse gas emissions. The alternatives included the currently used highway route (CR-550), an alternative highway route (CR-595) considered in the planning stage of the mine, and a conceptual rail route designed for the purpose of this study. This assessment was performed using two different methods; Detailed LCA and Operational LCA. The Detailed LCA incorporated the emissions arising from the complete life cycle of the transportation activity, including the construction, operation and maintenance phases of both Infrastructure and equipment. This method used SimaPro version 8 software along with Ecoinvent v3.1 database and several other custom datasets created using regional and study specific data. It is apparent from previous research that emissions from the “Operations” phase often account for a major portion of the overall impacts, so part of this research investigates whether a process that includes only the Operations phase emissions would still provide reliable outcomes. The Operational LCA method considered the emissions only from the operations phase activities and the life cycle of the fuels used from well to wheel. This method used the in-built database of GREET 2016 model, along with case specific data on fuel consumption and type of vehicles used. The LCA was performed for the currently expected mine life of 8 years and also for 9, 10, 15, and 20-year mine lives, as the ongoing explorations around the mine may offer potential for mine life extension(s).
