Brief History of High-Grade Iron Ore Mining in North

D uring the last 15 years researchers in Australia, Brazil, and South Africa have gathered evidence supporting hypogene fluids, focused by deep structures, as the primary agent responsible for upgrading some subeconomic to low-grade iron formations (30–35% Fe) to enriched "direct shipping" hard ore (55–68% Fe). The impetus for this work has been both to understand the genesis of known
