But the highgrade market as a whole extends further with around 500 million tonnes per year of global exChina iron ore supply grading above Fe. This volume also includes pellets and concentrate although Fastmarkets s analysis shows that prices for these products correlate more closely with the 65 Fe index than with the 62 Fe one.

62 fe high grade iron ore

The price spread between midgrade iron ore and highgrade products narrowed to under 10 per tonne in August amid a major uptrend in the seaborne market for the steelmaking raw material eating into the profitability of mill in China Prices for 62 Fe iron ore were largely above 120 per tonne cfr

Iron Ore Geoscience Australia

The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral. It is nonmagnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s.

Iron Ore Quality a Potential Headwind to Green Steelmaking IEEFA

DRI steelmaking requires a higher grade of iron ore than blast furnaces the dominant global process. DRgrade iron ore ideally has an iron (Fe) content of 67 or more and such deposits are scarce only a small percentage of global seaborne iron ore comes close to DRgrade (Figure A). Figure A Seaborne Iron Ore Supply by Fe Content ( )
