washed copper slag. These metals exist in the forms of oxides. Washed copper slag has a high percentage of iron (Fe) followed by aluminium (Al), calcium (Ca), copper (Cu), zinc (Zn) and magnesium (Mg). The predominant chemical compositions are mainly iron compounds (eg. ferrosilicate, Fe 2 Si 2 O 6). Washed copper slag has a density of about
