Beskrivning

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.

Mer om författaren

Ram Pravesh Bhagat (born October 1954 has 36 years of research experience in the iron ore beneficiation & agglomeration areas while serving premier R&D establishments, SAIL-RDCIS and CSIR-NML. He has worked with Soviet Experts to implement R&D Projects at SAIL plants aimed to improve the productivity of sinter and its quality. In the 1990’s, the author research projects in collaboration with IIT Kharagpur, RAS Russia and with support from Private Industries. His subsequent research career in CSIR-NML (2000--2014) had been concentrated to the agglomeration area with support from the Ministry of Steel (Govt, of India), Private/ PSU Organisations, As a faculty member of AcSIR-CSIR and IIT (ISM), the author has developed courses in agglomeration technology and delivered invited lectures. He has supervised two Ph.D. scholars (IIT Kharagpur) and four M. Tech students (ISM). At ISM he initiated research in the field of agglomeration. He has contributed three book chapters including "Agglomeration" in the Encyclopedia of Iron, Steel, and Their Alloys (CRC Press). He has also published over a hundred research papers in journals and conference proceeding volumes. He is life fellow and member of several professional bodies. He is also recipient of various awards and fellowship including CSIR-DAAD.

Recensioner i media

Agglomeration of Iron Ores covers in considerable detail both the sintering and pelletising of iron ore fines and concentrates that are generated along with lump ore in iron ore mines around the world, either naturally or after upgrading in a beneficiation process. The book is devoted to a detailed treatise of the sintering and pelletising of the raw materials in separate chapters, including the fundamentals, mineralogy, reactions, process and operating variables, quality and productivity of sintering and pelletising. In summary, this book is a masterful coverage of the subject, and is recommended reading for metallurgical students, teachers, researchers, and practicing professionals in the iron and steel industry.--Ralph J Holmes, CSIRO Mineral Resources, Clayton, VIC, Australia, Mineral Processing and Extractive Metallurgy, April 2020
