Book Description
The rare earth elements and compounds have unique spectroscopic, magnetic and chemical properties. These materials not only provide interesting windows into many aspects of science but are being used in an ever increasing number of strategic applications, particularly in the high growth sectors of world economics such as electronics, environmental protection (catalysis), magnets, nuclear medicine therapy and agriculture.

Book Description
The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Book Description
Hydrometallurgy of Rare Earths: Extraction and Separation provides the basic knowledge for rare earth extraction and separation, including flow sheet selection criteria and related technology. The book includes the latest research findings on all rare earth separation processes, methods of controlling operation costs, and strategies that help lower wastewater and waste solid discharge. It discusses many real process parameters and actual situations in rare earth separation plants, also examining the basic principles, technologies, process parameters and advances and achievements in the area of rare earth extraction and separation. In addition, the book covers extraction separation theory as developed by Professor Guanxian Xu and Professor Chunhua Yan and the creative use of a computational simulation program to replace the bench scale and pilot plant tests and directly design rare earth extraction separation processes. - Outlines the theory of solvent extraction and separation of rare earths (REs) - Provides the necessary tools for a REs separation plant design - Includes a unique simulation program for the calculation of all process parameters - Includes Chinese nomenclature that is useful for identifying the various processes, also comparing it to the global literature

Book Description
Rare Earth Elements (REE) as well as tantalum and niobium are of tremendous importance because of their specific high-technology applications. The contributions gathered in this volume give an up-to-date survey on the mineralogy, primary ore deposits, prospecting, processing and applications of REE, Ta, and Nd, making this volume a useful handbook for practitioners and students. Finally, the comprehensive coverage of the fundamental aspects, especially as regards REE as tracers of geological phenomena, will prove extremely helpful.

Book Description
Modern Methods for the Separation of Rarer Metal Ions describes several separation methods of more than 50 elements. This book is divided into 19 chapters that include separation methods involving the actinide elements, rare earths, and many rarer elements of the main and transition groups of the periodic table. The introductory chapter discusses the principles of the separation techniques presented in this book. The remaining chapters explore the application of specific separation methods, such as ion exchange, chromatography, liquid-liquid extraction, distillation, and coprecipitation. The approach of each chapter is a presentation of separation principle of an element first followed by numerous examples of applications to the solution of practical problems encountered in separation chemistry. Chapters 2 and 3 examine the separations involving the actinides and rare earth elements using ion exchange and liquid-liquid extraction These are followed by chapters dealing with separations of other rarer elements, which have been arranged according to their position in the periodic table. These elements are: Li, Rb, Cs, Fr, Be, Ra, Ga, In, Tl, Ge, Ag, Au, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Tc, Re and the platinum metals. This book will be of great use to analytical chemists.

Book Description
Increased consumption of electronic equipment has brought with it a greater demand for rare earth elements and metals. Adding to this is the growth in low carbon technologies such as hybrid fuel vehicles. It is predicted that the global supply of rare earth elements could soon be exhausted. A sustainable approach to the use and recovery of rare earth elements is needed, and this book addresses the political, economic and research agendas concerning them. The problem is discussed thoroughly and a multi-disciplinary team of authors from the chemistry, engineering and biotechnology sectors presents a range of solutions, from traditional metallurgical methods to innovations in biotechnology. Case studies add value to the theory presented, and indirect targets for recovery, such as municipal waste and combustion ash are considered. This book will be essential reading for researchers in academia and industry tackling sustainable element recovery, as well as postgraduate students in chemistry, engineering and biotechnology. Environmental scientists and policy makers will also benefit from reading about potential benefits of recovery from waste streams.
