The veins reset once every thirty in-game days. Each vein has a chance to produce a precious gem. Iron Ore Veins may be mined with a pickaxe to obtain iron ore. Iron ore may be transmuted into silver ore using the Transmute Mineral Ore spell.
Iron ore is used to make iron ingots at a smelter from there, it can be used in creating and improving iron weapons and armor, as well as a number of materials in The Elder Scrolls V: Hearthfire.
