Why iron ore grade is now more important than ever - Stockhead
May 24, 2020 · Some impurities, such as phosphorus, are costly to remove and otherwise affect steel quality. So it makes sense that steelmakers want higher grade ore with less impurities. “There is a big difference between a 65 per cent ore and a 55 per cent ore – roughly three times the impurity levels,” Eames explained.

Iron ore - Wikipedia
The typical magnetite iron-ore concentrate has less than 0.1% phosphorus, 3–7% silica and less than 3% aluminium. Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S., Eastern Canada and Northern Sweden.
Why is hematite used over magnetite? Magnetite has more ...
Nov 11, 2017 · Magnetite has higher iron content than hematite. But hematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentrated before it can be used to produce steel.

Hematite - Wikipedia
Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
