Phosphate Rock: An Industry in Transition takes an interdisciplinary approach to dealing with the phosphate rock chain and its exploration, extraction, processing, fertilizer making, and storage and transportation. The book treats the subject from a global perspective, giving readers insights into what is happening in the emerging economies of the world and possible solutions to problems. It also provides all the parameters necessary to evaluate economic viability of undertaking a mining venture, taking into consideration demands of sustainable mining – social responsibly, environmental pollution control measures, community development, and precautions necessary for ensuring health and safety in the hazardous conditions of mining operations. In recent years, supply chain management has grown in importance as it forms tighter links in integration of key business processes from initial extraction of raw phosphate rock to end customers through different stages of process techniques. The book surveys the changes in technology, including many game-changing innovations that could transform mining. - Presents a purposive classification of resources, status of global phosphate rock reserves, and their life-indices - Covers mining conditions and possibilities of improvement in methods of exploration and environmental impact - Includes economic considerations for resource assessment, mining, quality control and supply problems
