The iron ore market is recovering after several years of tumbling prices because much of the excess low-cost supply has been absorbed, according to the world's fourth-largest producer.

Australia's Fortescue Metals Group reported a full-year net profit of $985 million, triple last year's $316 million net profit for the year to end-June, on the back of a sharp improvement in production costs. The company also hiked its final dividend by 500 percent to 12 Australian cents (9.1 U.S. cent) a share, up from just 2 cents in the same period last year.
