This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation process. It then describes fundamental principles of the sintering and pelletization processes, including formation of green mix through granulation and green balls as well as chemical reactions during sintering. Finally, it offers a brief description of iron making processes and correlations related to the agglomerates: quality parameters and BF productivity and coke rate.
