Mining serves three professions: Blacksmithing, Engineering and Jewelcrafting, so it's really good combined with any of these.
Learning Draenor Mining
You can learn Draenor Mining from the [A Treatise on Mining in Draenor] scroll. You will get this scroll by mining Blackrock Ore or True Iron Ore at Draenor. (100% drop chance). Don't mine in your Garrison's mine, it won't drop from there.
If it doesn't drop for you, make sure you don't already have one in your bags, or in your bank.
