Water in mineral processing proceedings of the first international symposium ; [First International Symposium on Water in Mineral Processing during the 2012 SME annual meeting in Seattle, Washington

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.
