  • Extracting iron from low quality ore PrimitiveTechnology

    May 24, 20160183;32;A blast furnace is actually pretty simple but it does require a very hot burning fuel (coke?) and precise control of the oxygen environment. All natural iron ores are oxides, you can't just melt liquid iron out of its ore, so they need to be ground up, reduced, melted, and protected from re oxidizing until cool (limestone as flux?).

Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle.
