Agglomeration of Iron Ores


Book Description

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.




Iron Ores and Iron Oxide Materials


Book Description

This book provides the multidisciplinary reading audience with a comprehensive state-of-the-art overview of research and innovations in the relationship between iron ores and iron ore materials. The book covers industrial sectors dealing with exploration and processing of iron ores as well as with advanced applications for iron ore materials and therefore entails a wide range of research fields including geology, exploration, beneficiation, agglomeration, reduction, smelting, and so on, thus encouraging life cycle thinking across the entire production chain. Iron remains the basis of modern civilization, and our sustainable future deeply depends upon our ability to satisfy the growing demand for iron and steel while decoupling hazardous emissions from economic growth. Therefore, environmental sustainability aspects are also broadly addressed. In response to socioeconomic and climatic challenges, the iron ore sector faces, this book delivers a vision for the new opportunities linked to deployment of the best available, innovative and breakthrough technologies as well as to advanced material applications.

Blast Furnace Ironmaking


Book Description

Blast Furnace Ironmaking: Analysis, Control, and Optimization uses a fundamental first principles approach to prepare a blast furnace mass and energy balance in ExcelTM. Robust descriptions of the main equipment and systems, process technologies, and best practices used in a modern blast furnace plant are detailed. Optimization tools are provided to help the reader find the best blast furnace fuel mix and related costs, maximize output, or evaluate other operational strategies using the ExcelTM model that the reader will develop. The first principles blast furnace ExcelTM model allows for more comprehensive process assessments than the 'rules of thumb' currently used by the industry. This book is suitable for undergraduate and postgraduate science and engineering students in the fields of chemical, mechanical, metallurgical and materials engineering. Additionally, steel company engineers, process technologists, and management will find this book useful with its fundamental approach, best practices description, and perspective on the future. - Provides sample problems, answers and assignments for each chapter - Explores how to optimize the blast furnace operation while maintaining required temperatures and gas flowrates - Describes all major blast furnace equipment and best practices - Features blast furnace operating data from five continents




Iron Ore


Book Description

Iron Ore: Mineralogy, Processing and Environmental Sustainability, Second Edition covers all aspects surrounding the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of the global infrastructure. The book explores new ore types and the development of more efficient processes/technologies to minimize environmental footprints. This new edition includes all new case studies and technologies, along with new chapters on the chemical analysis of iron ore, thermal and dry beneficiation of iron ore, and discussions of alternative iron making technologies. In addition, information on recycling solid wastes and P-bearing slag generated in steel mills, sustainable mining, and low emission iron making technologies from regional perspectives, particularly Europe and Japan, are included. This work will be a valuable resource for anyone involved in the iron ore industry. - Provides an overall view of the entire value chain, from iron ore to metal - Includes specific information on process/stage/operation in the value chain - Discusses challenges and developments, along with future trends in the iron ore and steel industries - Incorporates new, sustainable mining techniques

Recovery and Utilization of Metallurgical Solid Waste


Book Description

At present, a lot of metallurgical solid wastes have not been timely and effectively recycled, resulting in serious problems of environmental pollution and waste of resources. As a result, large-scale comprehensive utilization technologies have been initiated, including slag dry granulation technology, steel slag cement technology, slag wool technology, slag waste heat recovery technology, etc. The comprehensive utilization of metallurgical solid waste has attracted worldwide attention. It is an effective way to improve the utilization efficiency of resources and the added value of products by using scientific metallurgical solid waste recycling methods. This book intends to provide the reader with a comprehensive overview of metallurgical solid wastes comprehensive utilization technology. The comprehensive utilization methods of four representative metallurgical solid wastes are emphatically described, such as blast furnace slag, steel slag, tailings and metallurgical dust.




Ironmaking and Steelmaking Processes


Book Description

This book describes improvements in the iron and steel making process in the past few decades. It also presents new and improved solutions to producing high quality products with low greenhouse emissions. In addition, it examines legislative regulations regarding greenhouse emissions all around the world and how to control these dangerous emissions in iron and steel making plants.




Operations and Basic Processes in Ironmaking


Book Description

This textbook explores the production of pig iron, covering the first part of the steel production process, known as ironmaking. Divided into seven chapters, it discusses the following topics: raw materials for steel production (coking coal, iron ore, slag-forming agents and fluxes, scrap, ferroalloys and pre-reduced materials), the sintering process (used to prepare the burden for the blast furnace), the pelletizing process (used to agglomerate the fine iron ores), the production of coke (the main reductant in the ironmaking process), the production of iron by reduction with gas (an alternative to the blast furnace) and the production of pig iron in the blast furnace (which is used in more than 65% of steel production worldwide). Specially conceived for graduate and undergraduate courses, this book is based on more than 30 years of teaching experience in courses for undergraduates, graduates (master and Ph.D.) and industry professionals (technicians). It explores the recent trends in the iron- and steelmaking process (which might used in the future production of steel), and features 55 worked exercises and real-world problems to complement of the theoretical sections of the text.
