The main components of magnesium slag:
Magnesium oxide (MgO) occupies most of its total mass. Magnesium slag also contains some other metal oxides, such as aluminum oxide (Al2O3), calcium oxide (CaO) and silicon oxide (SiO2).
(1) Magnesium slag is solid waste discharged during the Pidgeon process of magnesium smelting. The main components are CaO, SiO2, and unreduced MgO. Yes: CaO is 40%~50%, SiO2 is 20%~30%, Al2O3 is 4%~7%, MgO<5%, Fe2O3 is 2.5%~6.5%.
(2) The reuse of magnesium slag is mainly used in the cement industry, specifically calcined cement clinker, active mixed materials and cementitious materials.
