Following in the tradition of the first six editions, the goal of this successful, issues-based textbook, Chemistry in Context, seventh edition, is to establish chemical principles on a need-to-know basis for non-science majors, enabling them to learn chemistry in the context of their own lives and significant issues facing science and the world. The non traditional approach of Chemistry in Context reflects today's technological issues and the chemistry principles imbedded within them. The seventh edition applies sustainability principles wherever possible. Global warming, alternate fuels, nutrition, and genetic engineering are examples of issues that are covered in Chemistry in Context.

Features review questions at the end of each chapter; Includes suggestions for recommended reading; Provides a glossary of ecological terms; Has a wide audience as a textbook for advanced undergraduate students, graduate students and as a reference for practicing scientists from a wide array of disciplines

Wills' Mineral Processing Technology provides practising engineers and students of mineral processing, metallurgy and mining with a review of all of the common ore-processing techniques utilized in modern processing installations.

Chapters deal with each of the major processing techniques, and coverage includes the latest technical developments in the processing of increasingly complex refractory ores, new equipment and process routes. This new edition has been prepared by the prestigious J K Minerals Research Centre of Australia, which contributes its world-class expertise and ensures that this will continue to be the book of choice for professionals and students in this field.This latest edition highlights the developments and the challenges facing the mineral processor, particularly with regard to the environmental problems posed in improving the efficiency of the existing processes and also in dealing with the waste created. The work is fully indexed and referenced. · The classic mineral processing text, revised and updated by a prestigious new team · Provides a clear exposition of the principles and practice of mineral processing, with examples taken from practice· Covers the latest technological developments and highlights the challenges facing the mineral processor· New sections on environmental problems, improving the efficiency of existing processes and dealing with waste.

Introduction to Mineralogy consolidates much of the material now covered in traditional mineralogy and optical mineralogy courses and focuses on describing minerals within their geologic context. It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

Compiled with the help of a team of specialist contributors, Dictionary of Earth Sciences is the most authoritative and wide-ranging dictionary of earth sciences available in a single volume. The 6,000 entries provide broad coverage of climatology, economic geology, geochemistry, oceanography, petrology, and volcanology. There are entries on planetary science, remote sensing, statistics, and sequence stratigraphy, and substantial updating in palaeontology, mineralogy, and geophysics. A useful section of appendices includes wind strengths and time scales. Substantially revised and updated for this new edition, Dictionary of Earth Sciences is an essential reference for all students of earth science and anyone else with an interest in the earth.

This is the first and only book that explains in non-technical terms how to use pocket, portable and laboratory instruments to identify diamonds and coloured gems and to separate them from imitations and 'look-alikes'. The book's approach is direct and practical, and its style easy to understand. In fact, with this highly accessible guide, anyone can begin to master gem identification. Using a simple, step-by-step system, the authors explain the proper use of nine essential but uncomplicated instruments that will do the identification tasks, what to look for gemstone by gemstone, and how to set up a basic lab at modest cost. Three of the instruments are inexpensive, portable, pocket instruments which, when used together, can identify almost 85 per cent of all precious and popular stones. The key to avoiding costly mistakes and recognizing profitable opportunities is knowing both what to look for and what to look out for. "Gem Identification Made Easy" will help you: open your eyes to the types of imitations, synthetics, look-alikes and fakes that can be encountered in today's gem and jewellery world; learn how to tell the difference between them; recognize the limitations of your own skill and when to employ the services of a professional gemmologist or laboratory; and become professional in your business or hobby. Most of all, it will help you become less dependent on what you're told and more dependent on you own gem knowledge.

An overview of the prehistoric substance amber and its fossilized inclusions, this text describes how it is formed from the resin of ancient trees and where it is found. It tells how to distinguish genuine amber from fake, describes its uses, and recounts the search for DNA from insect inclusions.
