Book Description
The development of new technologies and the increasing demand for mineral resources from emerging countries are responsible for significant tensions in the pricing of non-ferrous metals. Some metals have become strategic and critical because they are used in many technological applications such as flat panel TVs (indium), solar panel cells (indium), lithium-ion batteries for electric vehicles (lithium, cobalt), magnets (rare earth elements, such as neodymium and dysprosium), scintillators (rare earths), and aviation and medical applications (titanium); their availabilities remain limited. The secured supply of these metals is crucial to continue producing and exporting these technologies, and because the specific properties of these metals make them essential and difficult to substitute for a given industrial application. Hydrometallurgy have the advantages of being able to process low-grade ores, to allow better control of co-products, and have a lower environmental impact providing that the hydrometallurgical route is optimized and cheap. The need to develop sustainable, efficient, and cheap processes to extract metals from complex and poor polymetallic matrices is real. The aim of this book was to highlight recent advances related to hydrometallurgy to face new challenges in metal production.

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
This book is based on the undergraduate and MSc courses in hydrometallurgy which Professor A R Burkin gave from 1961 until he retired in 1988. It is divided into two sections. The first deals with the fundamental chemical and physical principles on which the technology is based. In the second, processes which are used for the production of individual metals are described, in terms of those principles where appropriate.

Book Description
Hydrometallurgy is one of the main routes for obtaining metals that are needed for society development and for our everyday life. Chapter One presents the basics of hydrometallurgy, namely its main stages leaching, purification and/or concentration of pregnant leach solutions (PLSs), and metals' recovery. Chapter Two focuses on the gold extraction processes that involve the use or addition of industrial grade oxygen to optimise the processes. In particular, it looks at how oxygen can be used to increase the throughput and/or gold recovery and make the processes more flexible. Chapter Three gives an overview of the microbially-mediated metal transformations in which iron oxides potentially provide an applicable biotechnological method for efficient removal of pollutants from ground waters and wastewaters. Chapter Four assesses the hydrometallurgical process based on leaching, deironization, and purification of bis(trifluoromethylsulfonyl)amide salt including RE components.

Book Description
Recent Advances in Mining and Processing of Low-Grade and Submarginal Mineral Deposits reviews advances in the mining and processing of low-grade and submarginal mineral deposits, taking into account the environmental considerations that increasingly are being regarded as a necessary prerequisite to acceptable mineral resources development. The focus is on marginal and sub-marginal ores, as well as ores of above normal cut-off grades which for some reason cannot be mined and/or processed economically at current technological or economic levels. This book is comprised of 12 chapters and begins with an overview of low-grade ore potential, followed by a discussion on the theoretical and practical aspects of in situ mining. Block cave-in place leaching, biological leaching of sulfide ores, and nuclear chemical mining of primary copper sulfides are also considered. Subsequent chapters explore the economics and safety of nuclear chemical copper mining; hydrometallurgy of low-grade copper ores; trends in process metallurgy; and environmental aspects of mining and processing low-grade and submarginal mineral deposits. This monograph should be of interest to mining officials and professionals.
