Dark Iron is a special resource that can not be found in a few select areas. There are not many uses for Dark Iron except to make some gear with fire resistance and epic weapons forge. Engineers can also use Dark in some of their income and it is used as part of the Warlock epic mount quest for land and wow gold. All the ore you get can be melted inside the black wrought Blackrock Depths. Since Dark Iron is a special resource and can not be melted at the Black Forge I do not recommend farming dark iron at your workplace.

However, if you need Dark for a quest or your profession, here are the best places to farm it. Since the outbreak, the dark iron ore can be found in the bodies. So if you want the ore you have to venture into the Blackrock Depths and Molten Core to get it. There are some works fine that can be performed inside Blackrock Depths (49-56) with cheap wow gold, I recommend that you try to get some groups in there if you are the recommended level of the area or just run in instance if you're high enough level where you can either solo the elite groups or just walk past them without aggroing them.

Unfortunately, I have not a route map, but it's easy to return after crossing the body only once. You can also find the Dark Heart of Magma (61-63). Winter is loaded with thorium. There are many choices and strategies for you in this area. You can stick to the execution of the loop on the map or a stick in the caves you find. You can even go out of the route on the map if you wish. You should have much luck with this circuit zone.The you spin (or driving) in Silithus is a large square.

If this route is too boring for you there are tunnels / caves that you can go in, but you'll have to fight monsters. This area is another good place to farm thorium Oregon. The Blasted Lands is another good area to collect thorium in and world of warcraft gold in the game. You can travel the route on the map and find both thorium and rich thorium veins. Be sure to enter the cave in the northern part of the peninsula route.Hellfire is probably the best area and you will only need to go to mine Fel.

The way I recommend is extremely broad and there are very high densities of mines throughout the area. The area around Hellfire Citadel in the center of the map is a very good spot, you can simply run a loop through them while grinding and no shortage of Fel Iron deposits to mine. Be careful when you cross the Fallen Sky Ridge in the northwest, as it is full of level 63 elite giants.
