Although many available metal recycling methods are simple and fast, they are also expensive and cause environmental pollution. Biohydrometallurgical processing of metals offers an alternative to overcome these issues, as the use of biological means not only helps to conserve dwindling ore resources but also fulfills the need for the unambiguous need to extract metals in nonpolluting, low-energy, and low-cost way. This book covers biohydrometallurgy and its application in the recovery of metals from secondary sources like wastes. It aims to provide readers with a comprehensive overview of different wastes for metal recovery and biological treatment methods that are both environmentally friendly and economically viable.

Nanotechnology for Battery Recycling, Remanufacturing, and Reusing explores how nanotechnology is currently being used in battery recycling, remanufacturing and reusing technologies to make them economically and environmentally feasible. The book shows how nanotechnology can be used to enhance and improve battery recycling, remanufacturing and reusing technologies, covering the fundamentals of battery recycling, remanufacturing and reusing technologies, the role of nanotechnology, the separation, regeneration and reuse of nanomaterials from battery waste, nano-enabled approaches for battery recycling, and nano-enabled approaches for battery remanufacturing and reusing. This book will help researchers and engineers to better understand the role of nanotechnology in the field of battery recycling, remanufacturing and reusing. It will be an important reference source for materials scientists and engineers who would like to learn more about how nanotechnology is being used to create new battery recycling processes. - Outlines practical and cost-efficient processes for recycling and reusing batteries - Highlights the different types of nanomaterials used in battery recycling processes - Assesses major challenges with integrating nanotechnology into battery manufacturing processes on an industrial scale

This landmark publication distills the body of knowledge that characterizes mineral processing and extractive metallurgy as disciplinary fields. It will inspire and inform current and future generations of minerals and metallurgy professionals. Mineral processing and extractive metallurgy are atypical disciplines, requiring a combination of knowledge, experience, and art. Investing in this trove of valuable information is a must for all those involved in the industry—students, engineers, mill managers, and operators. More than 192 internationally recognized experts have contributed to the handbook’s 128 thought-provoking chapters that examine nearly every aspect of mineral processing and extractive metallurgy. This inclusive reference addresses the magnitude of traditional industry topics and also addresses the new technologies and important cultural and social issues that are important today.

Mineral processing technologies have been used for decades to protect the environment and many examples of such applications are given here. The book covers four major subject areas: fundamentals; environmental pollution and its prevention; separation processes; and innovative techniques. Audience: Scientists, engineers and technologists conducting both applied and basic research into the different environmental aspects of mineral processing.

The application of microbiological methods to the extraction of metals from minerals is supported by several bioleaching and biooxidation processes operating in different sites over the world. This book details the basic aspects of the process with special emphasis on recent contributions regarding the chemical and microbial aspects of the bioleaching process and the use of microorganisms in the treatment of complex ores and concentrates.

This book explores the concept and methods of waste management with a new approach of biological valorization. Waste valorization is a process that aims to reduce, reuse, and recycle the waste into usable, value-added, and environmental benign raw materials which can be a source of energy. The book brings together comprehensive information to assert that waste can be converted into a resource or a raw material for value addition. Waste valorization imbibes the natural recycling principles of zero waste, loop closing, and underlines the importance of sustainable and environmentally friendly alternatives. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the contours of waste valorization principles, biovalorization technologies for diverse group of wastes including agricultural, municipal, and industrial waste. It further discusses the emerging paradigms of waste valorization, waste biorefineries, valorization technologies for energy, biofuel, and biochemical production. The book meets the growing global needs for a comprehensive and holistic outlook on waste management. It is of interest to teachers, researchers, scientists, capacity builders and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of biotechnology and environmental sciences.
