Available in PDF, EPUB and Kindle. Book excerpt: Today large numbers of geoscientists apply thermodynamic theory to solu tions of a variety of problems in earth and planetary sciences. For most problems in chemistry, the application of thermodynamics is direct and rewarding. Geoscientists, however, deal with complex inorganic and organic substances. The complexities in the nature of mineralogical substances arise due to their involved crystal structure and multicomponental character. As a result, thermochemical solutions of many geological-planetological problems should be attempted only with a clear understanding of the crystal-chemical and thermochemical character of each mineral. The subject of physical geochemistry deals with the elucidation and application of physico-chemical principles to geosciences. Thermodynamics of mineral phases and crystalline solutions form an integral part of it. Developments in mineralogic thermody namics in recent years have been very encouraging, but do not easily reach many geoscientists interested mainly in applications. This series is to provide geoscientists and planetary scientists with current information on the develop ments in thermodynamics of mineral systems, and also provide the active researcher in this rapidly developing field with a forum through which he can popularize the important conclusions of his work. In the first several volumes, we plan to publish original contributions (with an abundant supply of back ground material for the uninitiated reader) and thoughtful reviews from a number of researchers on mineralogic thermodynamics, on the application of thermochemistry to planetary phase equilibria (including meteorites), and on kinetics of geochemical reactions.

Download or read book Clays in the Minerals Processing Value Chain written by Markus Gräfe and published by . This book was released on 2017 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clays are increasingly becoming a major problem in the mining, extraction and value-adding processes for a wide range of commodity raw materials. Clays can impact negatively on virtually every unit process within the mining and minerals processing sector, having long-term environmental implications that go well beyond the lifetime of the mining operation. This book is the first to compile, explain and evaluate the effects of clays in the mineral processing value chain, from mining to minerals processing, and finally, tailings disposal. Focusing on topics from the chemistry and rheology of clays to their detection and dissolution behaviour, this book provides comprehensive coverage of the effects on processes such as settling, preg-robing, flotation and comminution. It is an excellent reference for professional mineralogists and geologists, industrial engineers, and researchers interested in clays and clay minerals.

Download or read book Science and Conservation for Museum Collection written by Bruno Fabbri and published by Nardini Editore. This book was released on 2017-06-06 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of the book “Science and Conservation for Museum Collections” was born as a result of the experience made by CNR-ISTEC (Faenza) in the implementation of a course for Syrian restorers at the National Museum in Damascus. The book takes into consideration archaeological artefacts made out of the most common materials, like stones (both natural and artificial), mosaics, ceramics, glass, metals, wood and textiles, together with less diffuse artefacts and materials, like clay tablets, goldsmith artefacts, icons, leather and skin objects, bones and ivory, coral and mother of pearl. Each type of material is treated from four different points of view: composition and processing technology; alteration and degradation causes and mechanisms; procedures for conservative intervention; case studies and/or examples of conservation and restoration. Due to the high number of materials and to the great difference between their conservation problems, all the subjects are treated in a schematic, but precise and complete way. The book is mainly addressed to students, young restorers, conservators and conservation scientists all around the world. But the book can be usefully read by expert professionals too, because nobody can know everything and the experts often need to learn something of the materials not included in their specific knowledge. Twenty- two experts in very different fields of activity contributed with their experience for obtaining a good product. All they are Italian experts, or working in Italy, so that the book can be seen as an exemplification on how the conservation problem of Cultural Heritage is received and tackled in Italy. —————————————————— SCIENCE AND CONSERVATION FOR MUSEUM COLLECTIONS INTRODUCTION 1 – PREVENTIVE CONSERVATION 1.1 Introduction 1.2 International standards and guidelines 1.3 Environment-material interaction 1.4 Microclimate and monitoring 1.5 Handling works of art 1.6 Exhibition criteria 1.7 MUSA project: intermuseum network for conservation of artistic heritage Bibliography Acknowledgements 2 – STONE ARTEFACTS 2.1 What conservation means 2.2 Natural Stones 2.3 Artificial stones 2.4 Deterioration of the stone 2.5 Cleaning of stone artefacts 2.6 Consolidation and Protection 2.7 Case studies Bibliography 3 – MOSAICS 3.1 Manufacturing techniques 3.2 History of the mosaic 3.3 Degradation of mosaic 3.4 Restoration of mosaics 3.5 Case study Bibliography 4 – CERAMICS 4.1 Ceramic technology 4.2 Technological classification of ceramics 4.3 Alteration and degradation processes 4.4 Ceramic conservation and restoration 4.5 Case studies 4.6 Examples of restoration Bibliography Acknowledgements 5 – CLAY TABLETS 5.1 Defnition 5.2 Deterioration 5.3 Conservative intervention 5.4 Case study: Syrian tablets Bibliography Acknowledgements 6 – GLASS 6.1 General information 6.2 Processing techniques 6.3 Glass deterioration 6.4 Glass conservation and restoration 6.5 Case studies Bibliography Acknowledgements 7 – METALS 7.1 Origin of metals 7.2 Manufacturing techniques 7.3 Conservation state of metals 7.4 Conservative intervention for metals 7.5 Case studies: Recovery of metallic artefacts from terracotta containers Bibliography Acknowledgements 8 – GOLDSMITH ARTEFACTS 8.1 Goldsmith’s metals 8.2 Enamels 8.3 Precious stones 8.4 Alteration and degradation 8.5 Conservative intervention 8.6 Case studies Bibliography 9 – WOOD ARTEFACTS 9.1 Characteristics of the wood 9.2 Working techniques 9.3 Degradation of wood 9.4 How to start restoring 9.5 Restoration of a small inlaid table 9.6 Restoration of a commemorating wooden tablet 9.7 The restoration of a seventeenth-century wooden crucifix Bibliography 10 – ICONS 10.1 The construction of icons 10.2 Degradation and damages of icons 10.3 Methods of conservation and restoration of icons 10.4 Examples of conservative interventions Bibliography 11 – TEXTILE FINDS 11.1 Morphology, characteristics and properties of textiles 11.2 Decay of textile fibres 11.3 Conservation treatments of archaeological textiles 11.4 Conservation practice: two case histories Bibliography Acknowledgements 12 – LEATHER AND ANIMAL SKIN OBJECTS 12.1 Introduction 12.2 Skin 12.3 The tanning process 12.4 Parchment 12.5 Leather degradation 12.6 Conservative intervention 12.7 Examples of conservative interventions Bibliography 13 – INORGANIC MATERIALS OF ORGANIC ORIGIN 13.1 The materials 13.2 The restoration operations 13.3 Cases of study Bibliography Acknowledgements 14 – ANALYTICAL TECHNIQUES 14.1 General information 14.2 Optical microscopy 14.3 Spectroscopic techniques 14.4 Radiochemical techniques 14.5 Chromatography 14.6 Electron microscopy 14.7 Thermal analyses 14.8 Open porosity measurements 14.9 Analysis of microbial colonization Bibliography Acknowledgements

Download or read book Surface Chemistry of Froth Flotation written by Jan Leja and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of froth flotation is an outstanding example of applied surface chemistry. It is extensively used in the mining, mineral, metallurgical, and chemical industries for separation and selective concentration of individual minerals and other solids. Substances so concentrated serve as raw materials for producing appropriate metals and chemicals. The importance of flotation in technology is chiefly due to the ease with which it can be made selective and versatile and to the economy of the process. The objective of this book is to review the fundamentals of surface chemistry together with the relevant aspects of organic and inorganic chemistry that-in the opinion of the author-are important ~ control of the froth flotation process. The review updates the information that had been available in books by Sutherland and Wark (1955), Gaudin (1957), Klassen and Mokrousov (1963), and GIembotsky et al. (1963). It emphasizes mainly the surface chemical aspects of the process, leaving other relevant topics such as hydrodynamics, mechanical and electrical technology, cir cuit design and engineering, operations research, instrumentation tech nology, modeling, etc., to appropriate specialized treatments.

Download or read book Applied Mineralogy in the Mining Industry written by W. Petruk and published by Elsevier. This book was released on 2000-11-29 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.

Download or read book Mineralogical Crystallography written by Jakub Plášil and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the dawn of structural crystallography, Walther Friedrich, Paul Knipping and Max von Laue carried out the first experiments and developed the theory of X-ray diffraction. From the early days, when even the simpler inorganic structures filled an entire PhD study, structural crystallography evolved at its own pace and found new partners in chemistry, physics, materials science, biology and other fields of physical sciences. Both morphological and structural crystallography, however, have remained as important instruments in the mineralogist's toolbox until today. Efforts to enhance the existing instrumentation, to improve our understanding of the theory of diffraction, to study nanoparticulate or poorly ordered materials, and to master large, complex structures continue in all fields of physical sciences. Mineralogy can thus use the fruits of this labour and include them in its toolbox.

Available in PDF, EPUB and Kindle. Book excerpt: By dividing the creation of matter, energy, life, and mind into three big bangs, Holmes Rolston III brings into focus a history of the universe that respects both scientific discovery and the potential presence of an underlying intelligence. Matter-energy appears, initially in simpler forms but with a remarkable capacity for generating heavier elements. The size and expansion rate of the universe, the nature of electromagnetism, gravity, and nuclear forces enable the the explosion of life on Earth. DNA discovers, stores, and transfers information generating billions of species. Cognitive capacities escalate, and with neural sentience this results in human genius. A massive singularity, the human mind gives birth to language and culture, increasing the brain's complexity and promoting the spread of ideas. Ideas generate ideals, which lead life to take on spirit. The nature of matter-energy, genes, and their genesis therefore encourages humans to wonder where they are, who they are, and what they should do.
