The digester commonly used consists of a steam-heated cylindrical vessel fitted with a central rotating shaft carrying a number of beater stirring arms.
This causes reduction of iron ore and the iron in the ore and sinter is melted out to form a pool of molten metal in the bottom, or hearth, of the furnace. The limestone combines with impurities and molten rock from the iron ore and sinter, forming a liquid slag which, being lighter than the metal, floats on top of it.
