An iron ore concentrate from the Iron Quadrangle area (Minas Gerais, Brazil) has been selected for the study. It is essentially composed of hematite with minor amounts of quartz as contaminant. Pilot-plant experiments have been conducted at a pilot-plant HPGR, which consists of a studded roll with 0.32 m in width and 1 m in diameter.

Yield is king when evaluating cost at the metallic iron unit stage, as well as at the liquid metal stage. However, iron unit yield from ore to liquid steel can vary over a wide range. Metallic iron unit losses can add up to greater than 15% during handling, storing, and melting of direct reduced iron (DRI).
