Difference Between Sponge Iron and Pig Iron Compare

Difference Between Sponge Iron And Pig Iron Compare

Apr 30, 2011 The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures.. Sponge iron and pig iron are different forms of iron that we can produce from iron ores that occurs naturally under the surface of
