Agglomeration of Iron Ores
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. It also describes process modeling and performance-related topics.

Ram Pravesh Bhagat is Professor (SAIL-NMDC Chair) at the Indian School of Mines (ISM) Dhanbad, India, which he joined in November 2014 after superannuation from the service of CSIR-National Metallurgical Laboratory (NML), Jamshedpur as Chief Scientist in October 2014. He has over 36 years of research experience in iron ore beneficiation and agglomeration at such organisations as R&D Centre for Iron & Steel (RDCIS)-SAIL, Ranchi and CSIR-NML. During the initial stage of his career at RDCIS (1978-1989), he worked with Soviet experts to implement R& D Projects in the Sintering Plant and Iron Ore Processing Units at Bhilai Steel Plant (BSP)-SAIL under the Bhilai Modernisation Program. In the 1990s, Prof. Bhagat pursued at NML research projects in the areas of beneficiation and dewatering in collaboration with IIT Kharagpur, RAS Russia, and with support from private industries. His subsequent research career at NML (2000-2014) concentrated on agglomeration and he initiated and executed several R&D projects sponsored by the Ministry of Steel, Government of India as well as private organisations, such as Tata Steel, MECON, and Tata Metaliks. Development of pilot scale pelletisation technology for Indian goethtic/ hematite ores, agglomeration of iron ore fines following nonconventional routes, improved granulometry, and cooling characteristics of sinter are some of his recently concluded projects. As a faculty member of AcSIR-New Delhi in the recent past and presently with ISM, Prof. Bhagat developed courses and delivered lectures in agglomeration technology. 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 45 research papers in SCI journals and 56 in conference proceeding volumes and delivered several invited lectures. Prof. Bhagat is a reviewer of national and international journals.He is also an examiner of Indian Universities. Prof. Bhagat receuved his M. Tech. from IIT Kanpur and Ph.D. from IIT Kharagpur. He is life fellow and member of several professional bodies. He is also recipient of various awards and fellowship including CSIR-DAAD.
