Book Description
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.

Book Description
Natural health practitioners believe that the body has all the necessary resources to heal itself. Nature has provided for it generously. Clays are perhaps some the most ancient remedies used by people and animals to accelerate healing in the most natural ways possible. Clays work in gentle, intuitive ways, by re-tuning the body systems and stimulating recovery. This is not to say that medicines should be abandoned in favour of clays. This is merely to say that clays have a well-deserved place in our health and beauty routines. The most important property of clay is to detoxify the body, due to its ability to attract positively-charged toxic ions (clay particles are negatively charged) and take them out of the body. A lot of our illnesses happen due to contamination of the body with toxins – both coming from the outside (environmental pollutants), and produced inside (metabolic toxins, such as free radicals, excessive hormones and other metabolic waste). In a healthy body toxins get eliminated by the body systems timely and efficiently. If the body resources are depleted due to stress, illness or fatigue, the removal of toxins is slowed down leading to their accumulation in fat and bone tissues, the brain, as well as other organs and muscles. Over time it can lead to serious health problems. Clays have a wonderful ability to work with the body, gently helping to remove heavy metals and other toxic waste. Clays, muds and salts are also wonderful natural cosmetic substances. They work on the skin by purifying it, regenerating the skin cells and improving blood circulation which ensures more nutrients reaching the skin. Oxygen gets delivered to skin cells more speedily and the removal of toxins and CO2 is facilitated. All this brings wonderful results – the skin becomes smooth, soft, pink, glowing, wrinkles get much less visible - skin regeneration takes place. Clays have been used by humans and animals since prehistoric times – to treat minor ailments, food poisoning, aches and pains, skin infections, mineral deficiency, in beauty rituals, as well as to make cosmetic products. The purpose of this book is to shed a bit more light on the scientific aspects of clays and clay-like minerals and their health-enhancing properties. I hope that you find it both educational and useful in more ways than one.

Book Description
Here is a comprehensive and up to-do-date presentation of the origins, and properties of clay minerals at the Earth ́s surface. The text reviews the relatively simple laws that govern the chemical or isotopic composition and the crystalline structure of clays, and then discusses their genesis and alteration. Concluding chapters show that clay minerals can form in variety of different environments: meteorites, lavas, subduction zones, among others.

Book Description
New two-dimensional materials based on clays and clay minerals are attracting attention for their outstanding properties that make them useful as hosts or supporting matrixes in applications such as pharmaceuticals, tissue engineering, environmental remediation, biosensors, filtration, wound dressings, drug delivery, and more. This book is a comprehensive overview of clay science and technology, focusing on synthesis, characterization, simulation, and applications. Chapters cover such topics as polymer–clay nanocomposites, the structure and properties of different clays, the use of clays for environmental remediation, and much more.

Book Description
This book provides a comprehensive and critical summary of clay mineral literature that relates to geology and geologic processes, making it useful both as a reference book for geologists and as a text for the specialist.The book encompasses the full scope of clay-shale geology. An introductory chapter provides basic background terminology and classification. This is followed by a relatively long chapter on the structure and composition of the various clay minerals. Chapter 3 provides an introduction to soil formation, chemical weathering, microbial alteration and the pedogenic formation of clay minerals. Chapters 4 and 5 cover the continental and marine transport, and deposition of clays. Both mechanisms and examples are presented, ranging from biodepositional to the nepheloid layer. Chapter 6 reviews data on the low to high temperature formation of clay minerals from marine volcanics, and the growth of authigenic clays in shallow marine, brackish, and evaporite environments. Chapter 7, Diagenesis Metamorphism, covers both burial diagenesis and the processes occurring during the conversion of shale to clay. Chapter 8 discusses the formation of authigenic-diagenetic formation of clays in sandstones. Chapter 9 describes the temperal distribution of clay minerals in North and South America, Europe, Africa and the Atlantic Ocean. The clay suites are related to factors such as continental drift, tectonics, climate and environment. The final brief chapter covers compaction, lithification and some general features of shales.The book is liberally sprinkled with x-ray patterns, chemical analyses, and SEM and TEM pictures, in addition to hundreds of examples.
