Tis text has resulted from some forty years of experience during which the author has puzzled over the meaning of ore textures. Te learning process has been slow and is still incomplete. Te bemusement began directly upon leaving the academic confnes, which in retrospect lef one keen young geologist very ill-equipped to interpret the mineralising process via feld or hand lens style observation of the rocks. Enlightenment has proceeded via a series of events:- 1. Te slow process of feld observation as an industry-based mine and exploration geologist. 2. Te opportunity to visit numerous diferent styles of ore deposit both as an academic and consultant. 3. Te need to answer questions from several generations of enquiring students. 4. Te privilege of being able to conduct research. 5. Te good fortune to be associated with a few top class economic geologists who actually knew what they were doing! Professor Willard C. Lacy deserves the most credit for quietly demonstrating the value of frst principles concerning fuid channelways, combined with an ability to look properly at the t- tures. Despite rapid technological advances this skill remains fundamental both to the practi- ing exploration geologist and to the academic researcher who is interested in understanding ore forming processes. Te fve volumes comprising this presentation were originally compiled individually over a period of eleven years, and aimed to progressively guide the observer though the principles of recogn-i tion concerning infll, alteration, overprinting, and fnally to ore-related breccias.

Introduction to Ore Microscopy is a brief introduction to the science of Ore Minerals. It is designed to help undergraduate and postgraduate students of Geology and Earth Science for their practical course. The book gives a comprehensive, handy and scientific description of ores which form a part of Ore Geology and Economic Geology. Illustrated with a wealth of full-colour and black-and-white polished section photographs, the book explains how to observe ores under the microscope in the reflected light. Besides dealing with the texture, structures, and paragenesis of ore minerals, it also deals with the methodology to study physical and optical characters of important ore minerals, such as Sulphides, Arsenides, Antimonides, Molybdenites, Tungstate, and Oxides ores. A brief description mineral paragenesis, paragenetic diagrams, and some important ore-deposits of India and other parts of the world are also given. The book will also prove to be useful for those working in the mineral industry.

This book presents recent developments in ore microscopy to support the work of engineers and scientists actively engaged in the field of mineral raw materials (processing plant engineers in mines, process mineralogists and chemists, exploration geologists, etc.) or in ore deposit research. Textural analysis must be rigorous, and simple to be practical. With this aim, the author proposes a specific and user-friendly systematic for textural analysis. A high-performance tool to acquire, quantify, and process the data applied for automated ore characterization is key to predict ore behavior, a fundamental aim of geometallurgy. The recently developed AMCO System (Automated Microscopic Characterization of Ores) provides the tool, first prototype available using computer vision coupled with reflected light microscopy. This innovation is introduced in the text and discussed through case studies of actual mining problems. This second volume of the book "A Practical Guide to Ore Microscopy" includes references, indexes, and other relevant information, plus Annexes 1 to 5. The latter include ore and gangue mineral indexes and mineral abbreviations (Annex 1), a brief compendium of common mineral associations in the main ore deposit types (Annex 2), an introduction to the procedures and techniques used to prepare polished sections (Annex 3), and the various tables used to identify common ores by direct microscopic observation (Annexes 4 and 5).

Provides an up-to-date introduction to the subject of ore microscopy, emphasizing the basic skills required for the study of opaque minerals in polished sections. Describes the modern ore microscope, the preparation of polished and polished-thin sections of opaque minerals and ores, and the identification of these minerals using both qualitative techniques and the quantitative methods of reflectance and microhardness measurement. Later sections discuss the interpretation of textural intergrowths of ore minerals and the determination of their paragenesis, along with the examination of coexisting minerals for determining their physio-chemical conditions of formation. Appendices contain the data necessary to identify approximately 100 of the more common ore minerals and those frequently encountered by the professional scientist.

Iron Ore: Mineralogy, Processing and Environmental Sustainability, Second Edition covers all aspects surrounding the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of the global infrastructure. The book explores new ore types and the development of more efficient processes/technologies to minimize environmental footprints. This new edition includes all new case studies and technologies, along with new chapters on the chemical analysis of iron ore, thermal and dry beneficiation of iron ore, and discussions of alternative iron making technologies. In addition, information on recycling solid wastes and P-bearing slag generated in steel mills, sustainable mining, and low emission iron making technologies from regional perspectives, particularly Europe and Japan, are included. This work will be a valuable resource for anyone involved in the iron ore industry. - Provides an overall view of the entire value chain, from iron ore to metal - Includes specific information on process/stage/operation in the value chain - Discusses challenges and developments, along with future trends in the iron ore and steel industries - Incorporates new, sustainable mining techniques

These proceedings comprise the peer-reviewed contributions submitted to the 11th International Congress for Applied Mineralogy (ICAM) held July 5-10, 2013, at the Southwest University of Science and Technology (SWUST) in Mianyang, China. The biennial ICAM is the most important gathering of applied mineralogists, organized every other year by the ICAM-Council. The multidisciplinary research presented in this book will be of interest to scientists and professionals dealing with topics like environmental and medical mineralogy; industrial minerals; bio-minerals and biomaterials; advanced materials; process mineralogy; mining and metallurgy; cultural heritage; the interaction of minerals with microorganisms; and solid waste treatment and recycling, including genetic mineralogy. “The field of applied mineralogy has been able to match society’s pace by continuously reinventing itself, quickly adopting new technologies and instrumentation as they became available and putting them to work for the service of mankind living in a world that heavily relies on minerals. Over the past few decades, applied mineralogy has evolved into a cutting- edge discipline that leads the way for science, engineering and research and development to benefit society. Contrary to popular belief, mineral resources are limited, and we have an obligation to our heirs to use them responsibly.” Dr. Maarten A.T.M. Broekmans Post-President ICAM Council

Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.

The Ore Minerals and Their Intergrowths focuses on the properties, characteristics, and reactions of ore minerals. The book first offers information on genetic systematics of ore deposits and ore textures. Discussions focus on meteorites, magmatic, sedimentary, and metamorphic sequences, fabric properties considered from a purely geometric point of view, genetic fabric types, and the relationship of ore textures with industrial minerals. The text then elaborates on annotation concerning the arrangement of materials and elements and intermetallic compounds. The publication takes a look at alloy-like compounds and tellurides and common sulfides and "sulfosalts". Topics include umangite, bornite, jalpaite, argentite, naumannite, crookesite, coloradoite, novakite, orcelite, maucherite, parkerite, and horsfordite. The manuscript further touches on oxide ore minerals and gangue minerals and non-opaque oxide ore minerals, including quartz, calcite, dolomite, siderite, cerussite, smithsonite, jarosite, tenorite, zincite, and cuprite. The text is a dependable reference for readers interested in ore minerals and their intergrowths.
