Ore Treatment an overview ScienceDirect Topics

Iron ore processing by Rio Tinto in the Pilbara region of Western Australia does not involve any chemical treatment. Flowsheets for the Brockman 2 and Paraburdoo processing plants are given in Figures 8.4 and 8.5 (Kinnel, 2013). The flowsheets are relatively simple. Dry processing involves up to three crushing circuits to produce lump and fines.
