Southern Africa is home to many important and interesting minerals, as well as a wide array of beautiful gemstones – including diamonds from South Africa, emeralds from Zimbabwe and tourmalines from Namibia. Minerals & Gemstones of Southern Africa is not only the most up-to-date publication on the minerals of Botswana, Eswatini, Lesotho, Namibia, South Africa, southern Mozambique and Zimbabwe, but also the first to feature the region’s gemstones. Mineral species descriptions detail their gemological properties, history, occurrence and uses, and are illustrated with striking full-colour photographs. The book includes: An introduction to the geology of the region. Detailed descriptions of minerals, including their gemological properties, history, occurrence and uses. Multiple full-colour photographs of the species. An invaluable guide for collectors, gemologists, students and anyone with an interest in earth sciences. Sales points: An important record of the region’s diverse mineral and gemstone heritage. Over 1 000 full-colour photographs. Concise, authoritative text.

Metallic Mineral Resources: The Critical Components for a Sustainable Earth serves the increasing interest in metal resources, especially the critical and strategic metals which are essential commodities for the green energy transition. The opening chapters introduce the heterogeneous distribution of metal resources as well as the industrial use of metals. The main chapters then work systematically through abundant metal systems, scarce critical metal systems, rare critical metal systems, trace critical metal systems, and precious metal systems. The book wraps with a close examination of temporal distribution of mineral resources and an insightful discussion of the future of mineral resources. Researchers and engineers in economic geology and mining and exploration industries will find themselves returning to this key reference for years to come.• Describes how mineable and economic metal concentrations form and are preserved in the Earth's upper crust • Explores how they are discovered by systematic mineral exploration at a variety of scales • Discusses how to educate the public on the scarcity of natural metal resources and the issues concerning the nexus between the energy transition and potential exhaustion of critical metals

The constant increase in the consumption of mineral resources, as well as the growing awareness of their exploitation, is causing deep concern within the scientific community. This concern is justified by the fact that the energy transition will increase the pressure on these resources, as renewable energies require an increased and more diversified quantity of mineral materials. This book presents an overview of the exploitation of these mineral resources, where the natural, regulatory and environmental constraints interfere with economic, financial and geopolitical interests. By mobilizing the fields of the humanities, geosciences and engineering, it also analyzes the challenges that the energy transition will encounter, challenges related to the contradictory effects that the acceleration of the extraction of these resources will have on their physical availability, the economies that exploit them and the populations that live off of them

This comprehensive textbook covers all major topics related to the utilization of mineral resources for human activities. It begins with general concepts like definitions of mineral resources, mineral resources and humans, recycling mineral resources, distribution of minerals resources across Earth, and international standards in mining, among others. Then it turns to a classification of mineral resources, covering the main types from a geological standpoint. The exploration of mineral resources is also treated, including geophysical methods of exploration, borehole geophysical logging, geochemical methods, drilling methods, and mineral deposit models in exploration. Further, the book addresses the evaluation of mineral resources, from sampling techniques to the economic evaluation of mining projects (i.e. types and density of sampling, mean grade definition and calculation, Sichel’s estimator, evaluation methods – classical and geostatistical, economic evaluation – NPV, IRR, and PP, estimation of risk, and software for evaluating mineral resources). It subsequently describes key mineral resource exploitation methods (open pit and underground mining) and the mineral processing required to obtain saleable products (crushing, grinding, sizing, ore separation, and concentrate dewatering, also with some text devoted to tailings dams). Lastly, the book discusses the environmental impact of mining, covering all the aspects of this very important topic, from the description of diverse impacts to the environmental impact assessment (EIA), which is essential in modern mining projects.

As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
