The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.
Rio Tinto Iron ore processing plants in the Pilbara region of Western Australia do not involve any chemical treatment. Flow sheets for the Brockman 2 (8.7 MTpa) and Mount Tom Price (28 MTpa) processing plants are given in Figs. 8.4 and 8.5 (Kinnel, 2013). The flow sheets are relatively simple.
