The Iron Mines mission is indeed the one that provides infusion.
Take people you trust with you on that mission, if you can. I originally went with a pickup group, and found myself having to do the mission again because the item required for the infusion was stolen from the group (the person intentionally logged off with the item, making it unavailable to all players).
Also, as a small hint, if you see a mursaat on that mission, you're going the wrong way. Try to take another path.
