Nov 28, 2018· All of the raw materials necessary for the smelting process -- iron ore, limestone and wood for charcoal were found in this self contained iron plantation Cornwall Iron Furnace, the only surviving intact charcoal cold blast furnace in the Western Hemisphere, attests to the once great iron industry that flourished in south central Pennsylvania
(6) By using low-grade iron ore that is unsuitable for sinter for the pre-reduction process, more low-grade iron ore is used for blast furnace process This also makes it possible to maintain the quality of iron ore used for sinter and improves the properties of sinter (7) The practice of blowing natural gas directly into the blast fur-
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil"
