What is Sponge Iron?
Direct Reduced Iron Sponge is a pellet that is removed by oxygen during immediate recovery, without the need for melting iron ore. Pellets) Porous which has a spongy appearance which is why it is called sponge iron. Sponge iron has a high grade of iron, which is more prevalent today due to the deficiency of iron waste and its high price as well as environmental problems.
The grade and amount of iron found in sponge iron is between 1 and 2 percent.
The high grade of sponge iron makes it a good source of iron and steel. As mentioned, the sponge can be obtained from recycled or processed iron ore that has not reached the melting temperature. Iron ore resuscitation in Iran is often accomplished using Midderox technology.
