Silico-manganese slag is a byproduct of silico-manganese alloy production, and its major oxide components are SiO 2, CaO, Al 2 O 3, and MnO. It's chemical composition similar to blast furnace slag, except it is more acidic due to higher SiO 2 and lower Cao and also contains ∼10 wt.% MnO. Depending on the process of cooling, the molten slag is ...
