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.

What is Slag? (with pictures)

 · Non-ferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process.

smelting - an overview | ScienceDirect Topics

The smelting process of this steel is to use the molten pig iron as the raw material without any fuel and to make steel with air being blown through the molten iron (the raw material) from the bottom or the sides of the converter, called pneumatic converter steel; if pure oxygen is used to replace the air, it is called the oxygen converter steel.

What is steel mill slag? - Quora

To the above, I would add only that the blast furnace slag results from the smelting of iron ore with fluxes, the BOF (oxygen converter) slag results from the removal of most of the carbon from the iron (using oxygen) with fluxes, thus making it steel, and the EAF (electric arc furnace) slag results from the melting of ferrous scrap with fluxes.
