One of the major challenges confronting the mining and minerals processing industry in the 21st century will be managing in an environment of ever decreasing water resources. Because most mineral processing requires high water use, there will be even more urgency to develop and employ sustainable technologies that will reduce consumption and the discharge of process-affected water. Water in Mineral Processing provides a comprehensive, state-of-the-art examination of this vital issue. A compilation of papers presented at the First International Symposium on Water in Mineral Processing, this book shares the insights of dozens of respected experts from industry and academia. A significant portion of the content is devoted to saline solutions and processing with sea water. Other chapters explore the latest in water treatment and biological methods, the effect of water quality on minerals processing, and water and tailings management. Water in Mineral Processing is an authoritative, first-of-its-kind resource that can help mining practitioners apply innovative water-use and purification technologies in the demanding years ahead.

The Draft Environmental Impact Statement (EIS) for the Stillwater Mining Company's (SMC) Revised Water Management Plans and Boe Ranch LAD describes the land, people, and resources potentially affected by the proposed revisions. The purpose of SMC's proposed revisions are twofold: 1) to develop and implement closure and post-closure water management plans for adit water, tailings impoundments, and storm water for the Stillwater and East Boulder mines; and 2) to construct and operate a pipeline and land application disposal system at SMC's Boe Ranch property, if needed, to dispose of treated adit and tailings waters from the East Boulder Mine during operations and at closure. This Draft EIS analyzes SMC's proposed revisions as well as agency-proposed modifications to the revised water management plan (e.g., reclamation cover requirements, reclamation cap design, use of biological treatment systems for treatment of undiluted tailings water at closure, relocation of tailings slimes as necessary to facilitate capping the tailings impoundments, and post-closure water routing and channel design). The major federal and state actions include the approval of all necessary permits to implement the revised water management plans, including construction and operation. The No Action Alternatives, Proposed Action Alternatives, and Agency-Mitigated Alternatives are analyzed in detail. The Preferred Alternatives are 3A, 3B, and 3C.

Forest land managers face the challenges of preparing their forests for the impacts of climate change. However, climate change adds a new dimension to the task of developing and testing science-based management options to deal with the effects of stressors on forest ecosystems in the southern United States. The large spatial scale and complex interactions make traditional experimental approaches difficult. Yet, the current progression of climate change science offers new insights from recent syntheses, models, and experiments, providing enough information to start planning now for a future that will likely include an increase in disturbances and rapid changes in forest conditions. Climate Change Adaptation and Mitigation Management Options: A Guide for Natural Resource Managers in Southern Forest Ecosystems provides a comprehensive analysis of forest management options to guide natural resource management in the face of future climate change. Topics include potential climate change impacts on wildfire, insects, diseases, and invasives, and how these in turn might affect the values of southern forests that include timber, fiber, and carbon; water quality and quantity; species and habitats; and recreation. The book also considers southern forest carbon sequestration, vulnerability to biological threats, and migration of native tree populations due to climate change. This book utilizes the most relevant science and brings together science experts and land managers from various disciplines and regions throughout the south to combine science, models, and on-the-ground experience to develop management options. Providing a link between current management actions and future management options that would anticipate a changing climate, the authors hope to ensure a broader range of options for managing southern forests and protecting their values in the future.

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.
