Land use was calculated following the approach described by Doka (2008). Based on an assumed generic final height of a tailings impoundment of 60 m and an assumed tailings density of 2200 kg/m3, a land area of 7.58E-06 m2 is required per kilogram of sulfidic tailings. The land is assumed to be converted from unknown origin to a disposal site.
