Download or read book Rare Earth Frontiers written by Julie M. Klinger and published by Cornell University Press. This book was released on 2018-01-15 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rare Earth Frontiers is a timely text. As Klinger notes, rare earths are neither rare nor technically earths, but they are still widely believed to be both. Although her approach focuses on the human, or cultural, geography of rare earths mining, she does not ignore the geological occurrence of these mineral types, both on Earth and on the moon.... This volume is excellently organized, insightfully written, and extensively sourced."―Choice Drawing on ethnographic, archival, and interview data gathered in local languages and offering possible solutions to the problems it documents, this book examines the production of the rare earth frontier as a place, a concept, and a zone of contestation, sacrifice, and transformation. Rare Earth Frontiers is a work of human geography that serves to demystify the powerful elements that make possible the miniaturization of electronics, green energy and medical technologies, and essential telecommunications and defense systems. Julie Michelle Klinger draws attention to the fact that the rare earths we rely on most are as common as copper or lead, and this means the implications of their extraction are global. Klinger excavates the rich historical origins and ongoing ramifications of the quest to mine rare earths in ever more impossible places. Klinger writes about the devastating damage to lives and the environment caused by the exploitation of rare earths. She demonstrates in human terms how scarcity myths have been conscripted into diverse geopolitical campaigns that use rare earth mining as a pretext to capture spaces that have historically fallen beyond the grasp of centralized power. These include legally and logistically forbidding locations in the Amazon, Greenland, and Afghanistan, and on the Moon.

Download or read book Application of Nanotechnology in Mining Processes written by Elvis Fosso-Kankeu and published by John Wiley & Sons. This book was released on 2022-01-31 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: b”Application of Nanotechnology in Mining ProcessesNanotechnology has revolutionized processes in many industries but its application in the mining industry has not been widely discussed. This unique book provides an overview of the successful implementation of nanotechnology in some of the key environmental and beneficiation mining processes. This book explores extensively the potential of nanotechnology to revolutionize the mining industry which has been relying for a very long on processes with limited efficiencies. The nine specialized chapters focus on applying nanoflotation to improve mineral processing, effective extraction of metals from leachates or pregnant solutions using nanoscale supramolecular hosts, and development of nano-adsorbents or nano-based strategies for the remediation or valorization of AMD. The application of nanotechnology in mining has so far received little attention from the industry and researchers and this groundbreaking book features critical issues so far under-reported in the literature: Application of nanotechnology in mineral processing for the enhancement of froth flotation Development of smart nanomaterials and application for the treatment of acid mine drainage Recovery of values from pregnant solutions using nanoadsorbents Valorization of AMD through formation of multipurpose nanoproducts. Audience Industrial interest will be from mining plant operators, environmental managers, water treatment plants managers, and operators. Researchers in nanotechnology, environmental science, mining, and metallurgy engineering will find the book valuable, as will government entities such as regulatory bodies officers and environmentalists.

Download or read book The Rare Metals War written by Guillaume Pitron and published by Scribe Publications. This book was released on 2020-08-04 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resources race is on. Powering our digital lives and green technologies are some of the Earth’s most precious metals — but they are running out. And what will happen when they do? The green-tech revolution has been lauded as the silver bullet to a new world. One that is at last free of oil, pollution, shortages, and cross-border tensions. Drawing on six years of research across a dozen countries, this book cuts across conventional green thinking to probe the hidden, dark side of green technology. By breaking free of fossil fuels, we are in fact setting ourselves up for a new dependence — on rare metals such as cobalt, gold, and palladium. They are essential to electric vehicles, wind turbines, solar panels, our smartphones, computers, tablets, and other everyday connected objects. China has captured the lion’s share of the rare metals industry, but consumers know very little about how they are mined and traded, or their environmental, economic, and geopolitical costs. The Rare Metals War is a vital exposé of the ticking time-bomb that lies beneath our new technological order. It uncovers the reality of our lavish and ambitious environmental quest that involves risks as formidable as those it seeks to resolve.
