2014 Minerals Yearbook

long-term price contracting buffered iron ore and steel margins from falling global prices; however, low-cost steel imports increased competition in the steel industry and reduced demand for domestic iron ore. U.S. iron ore production increased by 6% to 56.1 million metric tons (Mt) of usable ore in 2014 from 52.8 Mt in 2013.
