Recent Advances in Iron Ore Sintering AusIMM
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Due to the depleting reserves of traditional highgrade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia.
