Leveled mining on a couple of alts and as such I have a couple of guild bank tabs filled with ghost iron ore. Now I don't need this to level any other profession and so would like to make gold from it.
I have access to all professions across my toons so I can prospect/transmute/smelt it.
What would be the most efficient way to make money from it?
Personally, I smelt and transmute all of mine, mostly out of laziness. If you have mass quantities and the willingness to do it, doing the JC shuffle may net you more gold in the end.
Ive rarely ever made more by prospects vs selling out right mid to late expansion due to obscene undercutting. I have everything at 600 and find them all generally useless for income vs flat item farming on my dk or pally. That being said, server location has 100% effect on all of this.
Prospect it, use green gems to make necklaces and rings, use blue gems and cut them. If you have an enchanter disenchant to make dust, then make enchants and sell those.
