Iron ore is used to smelt iron bars and can be smelted with coal to make steel bars. Smelting iron ore into iron bars has a 50 success rate, unless the player is wearing a ring of forging, using superheat item, or using the blast furnace. Smelting iron ore into a bar gives 12.5 Smithing experience, smelting a steel bar gives 17.5 Smithing.

Blast furnaces cannot easily be switched on and off, so a shrewd approach to iron ore purchasing is needed to optimize their operating rates for different market conditions. Consumption of iron ore products can also be constrained by the end-use application that the steel producer is designing its product for.
Iron Ore. Vibration and Airblast Control. ... Careful blast design and planning, combined with prediction, measurement and reconciliation of results is the key to controlling and managing these outcomes and maintaining a good relationship with community and regulatory stakeholders.
The Ore Seller, run by Ordan in Keldagrim, sells iron ore for 25-75 coins each and can be found downstairs in the Blast Furnace factory in the eastern side of Keldagrim. As with most ores in Ordans stock, it is sold for much lower than its GE price, and tends to be out of stock except on skill total worlds.
