1. Introduction. Sintering is the main means to make the high-quality synthetic iron ore (synthetic iron ore is iron that has been sintered to produce a product that can be used similarly to real iron ore, which has more suitable drum strength, alkalinity, iron grade, and granulometry than normal standard iron ore).
Details
Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Owing to the depleting reserves of traditional high grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia.
