Slag - Wikipedia
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

The slag that comes off of that is not as hard and dense as steel slag. Steel slag is what happens when molten iron is introduced to other elements needed for steel, such as nickel, chromium, and manganese. The steel slag is much harder, making it harder to crush because of its higher compressive strength.
