Iron Ore to Sintering to Steelmaking - Analyzing Metals

U.S. iron ore production was estimated to have increased in 2018 owing to increased steel-mill-capacity utilization and higher steel demand. Raw steel production increased to 86.6 million tons in 2018 from 81.6 million tons in 2017. But before all that iron ore can be turned into steel, it must go through the sintering process. Sinter
