This book was written to provide a comprehensive survey of the current state-of-the-art information in coal preparation, with particular emphasis on coal desulfrization. The primary audience for this book will be practising coal preparation engineers who need complete information about all of the coal preparation and desulphurization technologies that are available now, or that may be available in the future. It will also be valuable for coal researchers who need details and comparative data for cutting-edge technologies that are still under development. The main emphasis is on physical coal preparation, but chapters also include chemical and biological technologies that are under development, but not yet used in industrial practice. Along with the successful technologies, also included are details of processes and techniques that were attempted, but were subsequently abandoned, along with discussions of the reasons they were abandoned.

The Science and Technology of Cement and other Hydraulic Binders covers the design of Portland Cement composition using the ideas and formulae of earlier scientists, including the calculation of proportions of different cement phases formed during processing. Other chapters cover cement manufacture by dry, semi-dry or wet processes using rotary and shaft kilns. Particular attention is given to the physical changes that occur in the raw mix when affected by chemical processes. The chemistry of clinker formation which is concerned chiefly with high temperature reactions in the solid-state phase or reactions in the presence of the liquid phase is also discussed. Users will find the latest information on the storage of cement, its packing and handling, hydration and setting, Gypsum, different mineral additions, and advances in special and newer cements, including blended cements, Portland slag cement, Pozzolanic cements, high alumina cements, high-strength cement-based materials, fiber-reinforced cement, non-Portland cements and lime. - Covers raw materials, cement design and manufacturing, fuels used in manufacturing, phase balances, clinker training, hydration and setting - Includes various types of cement, mineral additions, high strength cement and different cement-based materials - Presents information on activated alkaline materials, recycled cements and novel additions - Discusses future trends in cement manufacturing and the circular economy - Contains a high number of figures, tables and reference data

Mineral Processing Design and Operations is expected to be of use to the design engineers engaged in the design and operation of mineral processing plants and including those process engineers who are engaged in flow-sheets development.Provides an orthodox statistical approach that helps in the understanding of the designing of unit processes. The subject of mineral processing has been treated on the basis of unit processes that are subsequently developed and integrated to form a complete strategy for mineral beneficiation. Unit processes of crushing, grinding, solid–liquid separation, flotation are therefore described in some detail so that a student at graduate level and operators at plants will find this book useful. Mineral Processing Design and Operations describes the strategy of mathematical modeling as a tool for more effective controlling of operations, looking at both steady state and dynamic state models.* Containing 18 chapters that have several worked out examples to clarify process operations* Filling a gap in the market by providing up-to-date research on mineral processing* Describes alternative approaches to design calculation, using example calculations and problem exercises
