Applied Mineralogy in the Mining Industry

Applied Mineralogy in the Mining Industry PDF Author: W. Petruk
Publisher: Elsevier
ISBN: 0080527337
Category : Technology & Engineering
Languages : en
Pages : 287

Book Description
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.

Transforming Matter

Transforming Matter PDF Author: Trevor H. Levere
Publisher: JHU Press
ISBN: 0801873630
Category : Science
Languages : en
Pages : 344

Book Description
Chemistry explores the way atoms interact, the constitution of the stars, and the human genome. Knowledge of chemistry makes it possible for us to manufacture dyes and antibiotics, metallic alloys, and other materials that contribute to the necessities and luxuries of human life. In Transforming Matter, noted historian Trevor H. Levere emphasizes that understanding the history of these developments helps us to appreciate the achievements of generations of chemists. Levere examines the dynamic rise of chemistry from the study of alchemy in the seventeenth century to the development of organic and inorganic chemistry in the age of government-funded research and corporate giants. In the past two centuries, he points out, the number of known elements has quadrupled. And because of synthesis, chemistry has increasingly become a science that creates much of what it studies. Throughout the book, Levere follows a number of recurring themes: theories about the elements, the need for classification, the status of chemical science, and the relationship between practice and theory. He illustrates these themes by concentrating on some of chemistry's most influential and innovative practitioners. Transforming Matter provides an accessible and clearly written introduction to the history of chemistry, telling the story of how the discipline has developed over the years.

Flexoelectricity in Liquid Crystals

Flexoelectricity in Liquid Crystals PDF Author: Agnes Buka
Publisher: World Scientific
ISBN: 1848167997
Category : Science
Languages : en
Pages : 299

Book Description
The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Metabolic Engineering of Plant Secondary Metabolism

Metabolic Engineering of Plant Secondary Metabolism PDF Author: R. Verpoorte
Publisher: Springer Science & Business Media
ISBN: 9401594236
Category : Science
Languages : en
Pages : 288

Book Description
Plant secondary metabolism is an economically important source of fine chemicals, such as drugs, insecticides, dyes, flavours, and fragrances. Moreover, important traits of plants such as taste, flavour, smell, colour, or resistance against pests and diseases are also related to secondary metabolites. The genetic modification of plants is feasible nowadays. What does the possibility of engineering plant secondary metabolite pathways mean? In this book, firstly a general introduction is given on plant secondary metabolism, followed by an overview of the possible approaches that could be used to alter secondary metabolite pathways. In a series of chapters from various authorities in the field, an overview is given of the state of the art for important groups of secondary metabolites. No books have been published on this topic so far. This book will thus be a unique source of information for all those involved with plants as chemical factories of fine chemicals and those involved with the quality of food and ornamental plants. It will be useful in teaching graduate courses in the field of metabolic engineering in plants.

Thickening Fat

Thickening Fat PDF Author: May Friedman
Publisher: Routledge
ISBN: 0429017634
Category : Social Science
Languages : en
Pages : 360

Book Description
Thickening Fat: Fat Bodies, Intersectionality, and Social Justice seeks to explore the multiple, variable, and embodied experiences of fat oppression and fat activisms. Moving beyond an analysis of fat oppression as singular, this book will aim to unpack the volatility of fat—the mutability of fat embodiments as they correlate with other embodied subjectivities, and the threshold where fat begins to be reviled, celebrated, or amended. In addition, Thickening Fat explores the full range of intersectional and liminal analyses that push beyond the simple addition of two or more subjectivities, looking instead at the complex alchemy of layered and unstable markers of difference and privilege. Cognizant that the concept of intersectionality has been filled out in a plurality of ways, Thickening Fat poses critical questions around how to render analysis of fatness intersectional and to thicken up intersectionality, where intersectionality is attenuated to the shifting and composite and material dimensions to identity, rather than reduced to an “add difference and stir” approach. The chapters in this collection ask what happens when we operationalize intersectionality in fat scholarship and politics, and we position difference at the centre and start of inquiry.

History of Analytical Chemistry

History of Analytical Chemistry PDF Author: Ferenc Szabadváry
Publisher: Elsevier
ISBN: 1483157121
Category : Science
Languages : en
Pages : 430

Book Description
History of Analytical Chemistry is a systematic account of the historical development of analytical chemistry spanning about 4,000 years. Many scientists who have helped to develop the methods of analytical chemistry are mentioned. Various methods of analysis are discussed, including electrogravimetry, optical methods, electrometric analysis, radiochemical analysis, and chromatography. This volume is comprised of 14 chapters and begins with an overview of analytical chemistry in ancient Greece, the origin of chemistry, and the earliest knowledge of analysis. The next chapter focuses on analytical chemistry during the Middle Ages, with emphasis on alchemy. Analytical knowledge during the period of iatrochemistry and the development of analytical chemistry during the phlogiston period are then examined. Subsequent chapters deal with the development of the fundamental laws of chemistry, including the principle of the indestructibility of matter; analytical chemistry during the period of Berzelius; and developments in qualitative and gravimetric analysis. Elementary organic analysis is also considered, along with the development of the theory of analytical chemistry. This book will be helpful to chemists as well as students and researchers in the field of analytical chemistry.
