What is Direct Reduced Iron (with picture)

 · During the reduction process in the production of direct reduced iron either coal or a special gas — commonly containing a combination of carbon monoxide and hydrogen — is used. This mixture functions as a reducing agent and facilitates the decrease in the iron s oxygen and carbon content. The result is a type of iron that is 90-97 pure containing only minuscule amounts of carbon and
