Slag - Wikipedia

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.

Metal Profile: Iron Properties and Characteristics

Slag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production. Pig iron still contains between 3.5-4.5% carbon, along with other impurities, and is brittle and difficult to work with.
