WebAs iron bearing sedimentary minerals are deposited from the water column, they also become aligned with the existing magnetic field. The magnetism remains locked in the rock unless the rock is subsequently heated above the Curie Point, the temperature at which all magnets lose their magnetism. When the heated rock again cools below the Curie ... Web12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the
