Microscopy is a servant of all the sciences, and the microscopic examination of minerals is an important technique which should be mastered by all students of geology early in their careers. Advanced modern textbooks on both optics and mineralogy are available, and our intention is not that this new textbook should replace these but that it should serve as an introductory text or a first stepping-stone to the study of optical mineralogy. The present text has been written with full awareness that it will probably be used as a laboratory handbook, serving as a quick reference to the properties of minerals, but nevertheless care has been taken to present a systematic explanation of the use of the microscope as well as theoretical aspects of optical mineralogy. The book is therefore suitable for the novice either studying as an individual or participating in classwork. <...>

Since time immemorial the minerals, rocks and soil had been the major attraction for the growth, development, and survival of every living entity including human, animals, birds, plants, and trees. That indeed forced us to know more about the minerals (mineralogy) and the rocks and soils (petrology).

This book is intended for use in an introductory optical mineralogy course. The objective in preparing the book was to present in a single volume of reasonable size both a thorough treatment of optical theory as it pertains to mineral identification with the petrographic microscope, and detailed mineral descriptions of the common rock-forming minerais. The first seven chapters <leal with optical theory and provide an introduction to the properties oflight, a description of the petrographic microscope, and a discussion of the optical properties of isotropic and anisotropic materiais. Detailed step-by-step procedures have been included to guide students through the measurement of optical properties in both thin section and grain mount. Selected spindle stage techniques also are included. <...>

In 1963 the Chairman of Metallurgical Engineering at Queen’s University of Kingston, Ontario, Canada encouraged me to apply for a position in his department. This led to an appointment as an Assistant Professor of Metallurgical Engineering with a mandate to teach undergraduate and graduate courses in Mineral Process Engineering. Graduating metallurgists take positions available to them in the mining industry and mill “metallurgists” were in strong demand. Discussions with industry-oriented colleagues at the Department of Energy, Mines and Resources (Mines Branch) and with senior operators and plant design personnel at conferences such as the Conference of Metallurgists provided details of jobs available Canada-wide. This helped to fortify course content.

Quantitative modeling techniques and methods are central to the study and development of process engineering, and mineral processing is no exception. Models in mineral processing have been difficult to develop because of the complexity of the unit operations that are used in virtually all mineral recovery systems. Chief among these difficulties is the fact that the feed material is invariably a particulate solid. Many of the conventional mathematical modeling techniques that are commonly used for process equipment have limited application to particulate systems and models for most unit operations in mineral processing have unique features. Common ground is quite difficult to find. The one obvious exception is the population balance technique and this forms a central thread that runs throughout the modeling techniques that are described in this book. The models that are described are certainly incomplete in many respects, and these will be developed and refined by many researchers during the years ahead. Nevertheless, the models are useful for practical quantitative work and many have been widely used to assist in the design of new equipment and processes. Some of the newer models have not yet been seriously tested in the industrial environment <...>

Hillslopes occupy most of the land surface of the Earth. In areas of erosional topography the entire landscape, except the valley floors, consists of hillslopes. Consequently, hillslopes are a major focus of research in geomorphology. The study of hillslopes is essential not only in order to understand better the natural landscape but also for numerous practical reasons, such as controlling soil erosion and sedimentation on agricultural lands and mitigating the hazard posed by landslides. Geomorphologists have studied hillslopes since the latter part of the 19th century, but until the late 1950s their research focused almost exclusively on morphology. During the past 30 years, however, there has been a growing interest in hillslope processes, and today research on processes dominates this branch of geomorphology <...>

Geotechnical engineering is concerned with the application of civil engineering technology to some aspect of the earth, usually the natural materials found on or near the earth's surface. Civil engineers call these materials soil and rock. Soil, in an engineering sense, is the relatively loose agglomerate of mineral and organic materials and sediments found above the bedrock. Soils can be relatively easily broken down into their constituent mineral or organic particles. Rock, on the other hand, has very strong internal cohesive and molecular forces which hold its constituent mineral grains together. This is true for massive bedrock as well as for a piece of gravel found in a clay soil. The dividing line between soil and rock is arbitrary, and many natural materials encountered in engineering practice cannot be easily classified. They may be either a "very soft rock" or a "very hard soil." <...>
