Pyrite Ore - Wow Ore - Uldum - Kalimdor - Wow Zones - Get Wow Gold

The second best place to farm Pyrite Ore from is Uldum. In one hour you should be able to get 1 to 3 stacks of  pyrite ore, depending on how many competing wow ore miners you are up against. One stack of this wow ore averages between 50-200 wow gold from the auction house. If you smelt this into Pyrium Bar one stack can get you 300-600 wow gold from the auction house. Pyrite is a Cataclysm ore deposit, you should plan on lots of competing toons with the mining profession.

The image above shows the nodes I frequently farm. I consider pyrite to be a byproduct of farming Elementium Ore. A very lucrative byproduct.
