Iron Ore
The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits. Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but ...
