Limonite, like goethite, usually forms from the weathering of more primary iron ores like hematite or magnetite, but also from the oxidation and hydration of iron-rich sulfide minerals and more complex stuff like olivine (iron plus some other metal silicate; extremely common in the earth's crust but not stable close to the surface).

Iron is a Tier 4 metal. Iron can be refined through a complex process from its ores, which are hematite, magnetite or limonite. Iron may be smithed into a variety of tools, weapons, armor and items. It is a component for steel, the highest tier metal in the game.

Limonite has been used as a low-quality iron ore for thousands of years. Commercial mining of limonite as a source of iron is no longer done in areas where reasonable deposits of hematite and magnetite are present or readily imported. Limonite deposits are usually too small and too impure for use in modern metallurgy.

Before modern mineral analysis, the name "limonite" was given to many of the yellowish to yellowish brown iron oxides produced during the weathering of iron-bearing rocks or deposited as bog, lake, and shallow marine sediments.

It can be smelted at a smelter by a dwarf with the furnace operating labor activated to produce iron bars. It is, for all metalsmithing purposes, identical to magnetite and hematite. It has a noticeably lower solid density (read "weighs less") than the other iron ores and can thus be hauled to its destination more quickly than the other two ores.
