Rather, most iron ore compounds are polluted with sand, rock and silica. The process of extracting iron involves a number of steps. The first step to concentrate the iron ore and remove its contents of silica. To further remove any existing impurities, a complex process takes place in a blast furnace. The charge is where materials are placed into the blast furnace. These materials are: Ore, Limestone and Coke. A burst of hot, oxygen enriched air is blown into the air-blast nozzle located at the near bottom of the furnace. What follows are a number of oxidation and reduction type reactions which ultimately produce the metallic iron. One of these reactions is the coke being burnt. The heat generated by this reaction increases...
