  • Iron Ore

    Iron Ore (Fe) is mined in around 50 countries worldwide and used to make steel (buildings, cars, white goods etc.). Global economic growth is the primary factor that drives its supply and demand. When economies are growing, the need for steel in construction increases which drives the price up.
