Available in PDF, EPUB and Kindle. Book excerpt: Pyrite Oxidation and its Control is the single available text on the market that presents the latest findings on pyrite oxidation and acid mine drainage (AMD). This new information is an indispensable reference for generating new concepts and technologies for controlling pyrite oxidation. This book focuses on pyrite oxidation theory, experimental findings on oxidation mechanisms, as well as applications and limitations of amelioration technologies. The text also includes discussions on the theory and potential application of novel pyrite microencapsulation technologies for controlling pyrite oxidation currently under investigation in the author's laboratory.

Download or read book Implications of Pyrite Oxidation for Engineering Works written by A. Brian Hawkins and published by Springer Science & Business Media. This book was released on 2013-07-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book highlights and analyses the distress to buildings caused by sulphate-induced heave, with particular reference to the recent problems in the Dublin area of Ireland. It describes the formation of pyrite, the processes involved in its oxidation and the various ways in which consequential expansion takes place. For the first time in the literature it discusses the way that buildings can be raised above their supporting foundation walls by the expansion of pyritiferous fill which has been used beneath ground-bearing floor slabs in Ireland. The significance of fractures through the iron sulphide microcrystals for the rate and extent of oxidation is discussed. Photographs and profiles of sulphate ingress into concrete/concrete blocks are presented. Case histories from the UK, North America and Ireland are discussed.

Download or read book Final Technical Report. Reactivity of Iron-Bearing Minerals and CO2 Sequestration and Surface Chemistry of Pyrite. An Interdisciplinary Approach written by and published by . This book was released on 2014 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the course of the scientific program, two areas of research were pursued: reactions of iron oxides with supercritical CO2 and sulfide and surface reactivity of pyrite. The latter area of interest was to understand the chemistry that results when supercritical CO2 (scCO2) with H2 S and/or SO2 in deep saline formations (DFS) contacts iron bearing minerals. Understanding the complexities the sulfur co-injectants introduce is a critical step in developing CO2 sequestration as a climate-mitigating strategy. The research strategy was to understand macroscopic observations of this chemistry with an atomic/molecular level view using surface analytical techniques. Research showed that the exposure of iron (oxyhdr)oxides (which included ferrihydrite, goethite, and hematite) to scCO2 in the presence of sulfide led to reactions that formed siderite (FeCO3). The results have important implications for the sequestration of CO2 via carbonation reactions in the Earth's subsurface. An earlier area of focus in the project was to understand pyrite oxidation in microscopic detail. This understanding was used to understand macroscopic observations of pyrite reactivity. Results obtained from this research led to a better understanding how pyrite reacts in a range of chemical environments. Geochemical and modern surface science techniques were used to understand the chemistry of pyrite in important environmental conditions. The program relied on a strong integration the results of these techniques to provide a fundamental understanding to the macroscopic chemistry exhibited by pyrite in the environment. Major achievements during these studies included developing an understanding of the surface sites on pyrite that controlled its reactivity under oxidizing conditions. In particular sulfur anion vacancies and/or ferric sites were sites of reactivity. Studies also showed that the adsorption of phospholipid on the surface to selectively suppress the reactivity of these sites could of potential importance for suppressing acid mine drainage in the environment (a problem common to coal-mining sites). Biotic studies showed that microbial activity that promotes the oxidation of pyrite to produce AMD could also be suppressed by the adsorption of phospholipid.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Thermal Analysis and Calorimetry, Volume 1: Principles and Practice describes the basic background information common to thermal analysis and calorimetry in general. Thermodynamic and kinetic principles are discussed along with the instrumentation and methodology associated with thermoanalytical and calorimetric techniques. The purpose is to collect the discussion of these general principles and minimize redundancies in the subsequent volumes that are concerned with the applications of these principles and methods. More unique methods, which pertain to specific processes or materials, are covered in later volumes.

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory studies demonstrated the feasibility of using the Mossbauer effect and a backscattering mode of detecting 14.4 Kev gamma rays to spectroscopically monitor the oxidation processes taking place on pyrite materials. A cobaltous oxide form of cobalt-57 was the radiation source. Spectra were obtained of pyritic surfaces under 2 mm of water. Differentiation of nonoxidized and oxidized pyritic surfaces was possible with further separation of the spectra to show individual oxidation product peaks suggesting ferric hydroxide and ferric sulfate.

Available in PDF, EPUB and Kindle. Book excerpt: Infrared Thermography (IRT) is commonly as a NDE tool to identify damages and provide remedial action. The fields of application are vast, such as, materials science, life sciences and applied engineering. This book offers a collection of ten chapters with three major sections - relating to application of infrared thermography to study problems in materials science, agriculture, veterinary and sports fields as well as in engineering applications. Both mathematical modeling and experimental aspects of IRT are evenly discussed in this book. It is our sincere hope that the book meets the requirements of researchers in the domain and inspires more researchers to study IRT.

Download or read book Advances in the Characterization of Industrial Minerals written by G.E. Christidis and published by The Mineralogical Society of Great Britain and Ireland. This book was released on 2011-08-31 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advancement of human civilization has been intimately associated with the exploitation of raw materials. In fact the distinction of the main historical eras is based on the type of raw materials used. Hence, passage from the Paleolithic and Neolithic Age to the Bronze Age is characterized by the introduction of basic metals mainly copper, zinc and tin in human activities; the Iron Age is marked by the use of iron as the predominant metal. The use of metals has increased and culminated with the industrial revolution in the mid-eighteenth century, which marked the onset of the industrial age in the western world. Since then the importance of metals has gradually been surpassed by industrial minerals in the industrialized countries. Industrial minerals are raw materials used by industry for their physical and/or chemical properties. Characterization of industrial minerals is important for their assessment and can be demanding and often complicated. This new volume, co-published by the European Mineralogical Union and the Mineralogical Society of Great Britain & Ireland, is based on papers presented at an EMU-Erasmus IP School which was held in the Technical University of Crete, Chania, Greece. The aim of the School was to describe advances in some of the analytical methods used to characterize industrial minerals and to propose additional methods which are currently not used for this purpose.
