This article is about an older version of DF.

Ores are left behind after mining certain varieties of stone. Ore can be smelted to create bars of pure metal or combined to create alloys. Many ores are quite valuable as mined without being refined, and a mason or stone crafter can work them the same as any stone. However, ores fall into the economic stone category, and so must be designated for non-restricted use in the z-stone menu. Others can be combined when initially smelted into alloys, while others must first be made into bars of pure metal and then those combined to create the desired alloy - see the alloy article for details.

All ores are fire-safe material. Some are also magma-safe.

Note that in some cases ore value (given below) and metal value are not the same (Bismuth, Iron ores). Alloys, too, often have a higher value than the ores/metals they are made of. In most cases furniture made from the ore is as valuable as furniture made from a pure (non-alloy) metal, while requiring one-third the raw materials and significantly less processing.

Metal ores with two possible metals listed below always create the first metal when smelting, but have a chance of creating the second metal as well. Different rules apply to creating alloys.

Nearly all unmined ores are represented by the £ symbol. Exceptions are native aluminum, bismuthinite, and magnetite (which appear as ^, %, and ~, respectively), as well as cinnabar and cobaltite (which appear as £ but cannot be refined into mercury or cobalt as they would be in real life).

(L) - occurs in large clusters
(V) - occurs in veins
(S) - occurs in small clusters
1 - Note that raw adamantine/adamantine does not follow all the usual rules for an ore/metal in several respects - see article for full discussion.
2 - Due to a bug, native platinum actually occurs in olivine as small clusters rather than veins.
