This book is an excellent introduction to the increasingly complex field of nutrition and health for food technologists and health professionals. It includes individual entries for all major vitamins, minerals and trace elements. Information is provided on nutritional medicine and cell protective mechanisms, together with the role of vitamins, minerals, trace elements and essential fatty acids in treating and preventing disorders.
It's the classic work revised and updated! Identify over 500 of the most collectible minerals quickly and easily with this fully photographed field guide. And this new reissue makes identification easier, with new cleavability ratings for each entry alongside the handy classifications based on streak colour, Mohs' hardness and specific gravity. A complete introductory discussion of mineral forms and properties explains the essential criteria for recognition, and each of the hundreds of minerals (from Ankerite to Zinwaldite) is accompanied by information on its fracture, luster, chemical formula, aggregates, distinguishing characteristics and localities.
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.
This comprehensive textbook and reference manual presents concise, up-to-date information on mineral nutrition for livestock and poultry, as well as comparative aspects with laboratory animals and humans. Chapters are organized by established and most common minerals, and present information on each mineral's history, properties, distribution, and natural sources, as well as their requirements, metabolism, functions, deficiencies, supplementation methods, and toxicity for various animals. Those minerals for which naturally occurring deficiencies or excesses are known to be of economic importance are emphasized. A unique feature of this book is the description of the practical implications of mineral deficiencies and excesses, and of the conditions that might result. A large number of classic photographs illustrate mineral deficiencies and toxicities in farm livestock, laboratory animals and humans. Furthermore, it places strong emphasis on mineral supplementation in each chapter, and devotes an entire chapter to this subject.
