Magnetite is an iron ore used in making wrought iron and pig iron. Magnetite rocks are a dull, dark gray and are very hard to tell apart from cassiterite and galena.
Magnetite spawns as small rocks on the surface, indicating a vein somewhere below.
Magnetite veins are medium in size and can be found in igneous etrusive layers of stone:
- Rock salt
Magnetite can be smelted in a bloomery to produce a raw iron bloom, which is used to create wrought iron. Magnetite can be smelted in a blast furnace to produce liquid pig iron, which is used to create steel. Magnetite cannot be smelted in a fire pit, pit kiln, or crucible.
