Smelt reduction for iron and steel sector

Definition: Smelting reduction processes are the latest development in pig iron production. These processes combine the gasification of coal with the melt reduction of iron ore. Energy intensity of smelting reduction is lower than that of blast furnace, as the for coke production is not needed and the need for ore preparation is reduced. The

Iron ore

Magnetizing roasting uses temperatures between 700 and 900 C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting. For magnetizing roasting it is important to have a reducing atmosphere to prevent oxidization and the formation of Fe 2 O 3 because it is harder to separate as it is less magnetic.
