Mining of the low-grade iron formation, or chert-magnetite ores, began during the 1950s. At about 25 to 30% mid-recoverable iron, these low-grade ores are beneficiated and upgraded to high-grade iron ore concentrates with an iron content of approximately 65%. To date, approximately 1.6 billion tons of high-grade iron ore pellets have been
