Ilmenite and magnetite mining from hard-rock ore. Based on Tellnes mine (Norway) and Lac Allard mine (Canada).
Comments on modelling. All the flows related to energy consumption are based on U.S. Department of Energy survay from 2007 on Mining Industry (http://www1.eere.energy.gov/manufacturing/industries_technologies/minin…). The emissions are based on limestone quarry operation and production datasets. The land use and occupation is based on rough measurements from map.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
