Since talc is a hydrated magnesium sheet silicate, the concentration of SiO 2 and MgO (main constituents of talc) are at their lowest levels in the tailings and CaO, Al 2 O 3 and Fe 2 O 3 (the waste in the talc) are at their highest values at the depressant dosage of 1.2 kg/ton. Therefore in the recovered talc or mass, these substances are at
