The areas where these types of iron are produced are indicated on this map along with areas where iron ore production is under development and areas where other known principal occurrences of iron ore are found. The roles of the component plants of the industry may be assessed by some of their products. Blast furnace plants produce pig iron. Iron and steel furnace plants produce iron, steel and alloy steel casings and ingots. Ferro-alloy plants produce such materials as ferrosilicon, ferrophosphorous, ferromanganese, silicomanganese and ferrochrome. These are required by other plants for addition to the molten…
