If you were to sell the Ore (120GP) or Bars 276GP) each, it would take... - 8334 Iron Ores. - 3624 Iron Bars. ...to gain 1,000,000GP. Note that if you were to buy the Ore at 120gp, smelt into a Bar and sell for 276gp, you would make 156gp per Bar (Assuming none are lost in the refining process). Using this, it would take... - 6411 Iron Ore to be made into Iron Bar. (Granting 80,317.5 Smithing Exp). ...to make 1,000,000GP.
