Difference Between Iron Ore and Iron

Iron is extracted from its ore through removal of oxygen, which is a process called its reduction. Another process is through blast furnace where the ore is heated with carbon (coke). Iron thus produced using coke in blast furnaces is called pig iron, while iron produced through direct reduction is called sponge iron.

The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration. The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove clay, sand, etc.

Iron was made by smelting iron ore or heating the ore up to melting point. The liquid iron was then cast into ingots, called pigs. The pig iron could then either be reheated until it was molten and cast into moulds, or heated and hammered into bars of wrought iron. Of the two, wrought iron was more malleable and less brittle.

Enhancing Direct Reduced Iron (DRI) for Use in Electric Steelmaking

Currently, pig iron is mainly produced through the blast furnace route. Blast furnace operation and its ancillary processes contribute the largest amount of CO 2 per ton of steel production, due to use of coal and coke. DRI processes, which are based on natural gas, produce less than half of the CO 2 emissions of a blast furnace.
