Ore Veins appear throughout the world of Skyrim. They look like striped rocky areas. They can often be found within mines, but also out in the open. Ore is extracted from veins using a pickaxe. Typically, each vein yields three (3) pieces of ore and occasionally a random gem. Once a vein has been mined, it becomes depleted and cannot be immediately mined again, however, the ore will eventually respawn though the period is not currently known.
