Iron ore is unrefined iron located all over Runescape. A player must have a mining level of at least 15 to mine a iron ore. Each ore grants 35exp when mined. Iron ore rocks respawn time can vary from 5-20seconds depending on world population. If done correctly mining and dropping iron ore can give around 35k xp/hour. 


Smithing iron ore only requires one iron ore although the succes rate when using a furnace is 50%. When a player uses Superheat Item or a ring of forging however that chance increases to 100%
