In that ~100 year period the price changed only once, from A$2/tonne to A$9/tonne in 1965. Since 2003 the iron ore price has fluctuated, reaching a peak of ~A$120/t in 2011. Since then the price has fallen in an erratic but steady decline some 40% to a September 2014 price of A$85-90/t. Back to top.
