New discoveries of the properties of gold at a nanoscale, and its effective use in modern technologies, have been driving a virtual 'gold rush'. Depleting natural resources has meant that the recovery of gold continues to grow in importance and relevance.The Recovery of Gold from Secondary Sources analyses the most advanced technology in gold recovery and recycling from spent sources of mobile phones, unwanted electronic equipment and waste materials. State-of-the-art techniques of hydrometallurgical and bio-metallurgical processing, leaching, cementing, adsorbing and separation through bio-sorbents are all described in detail, providing a guide for students and researchers. Discussion of environmentally friendly methods of recovery are presented, in order to provide modern-day alternatives to previous techniques. For those interested in the study of gold recovery this book gives a comprehensive overview of current recovery, making it the ultimate source of information for students, researchers, chemists, metallurgists, environmental scientists and electronic waste recovery experts.

The history of gold begins in antiquity. Bits of gold were found in Spanish caves that were used by Paleolithic people around 40,000 B.C. Gold is the "child of Zeus," wrote the Greek poet Pindar. The Romans called the yellow metal aurum ("shining dawn"). Gold is the first element and first metal mentioned in the Bible, where it appears in more than 400 references. This book provides the most thorough and up-to-date information available on the extraction of gold from its ores, starting with the miner alogy of gold ores and ending with details of refining. Each chapter con cludes with a list of references including full publication information for all works cited. Sources preceded by an asterisk (*) are especially recom mended for more in-depth study. Nine appendices, helpful to both students and operators, complement the text. I have made every attempt to keep abreast of recent technical literature on the extraction of gold. Original publications through the spring of 1989 have been reviewed and cited where appropriate. This book is intended as a reference for operators, managers, and designers of gold mills and for professional prospectors. It is also designed as a textbook for extractive metallurgy courses. I am indebted to the Library of Engineering Societies in New York, which was the main source of the references in the book. The assistance of my son, Panos, in typing the manuscript is gratefully acknowledged.

Gold extraction or recovery from its ores may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners. Hydraulic mining was used widely in the Californian gold rush, and involved breaking down alluvial deposits with high-pressure jets of water. Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used.

Sustainable Resource Management Learn how current technologies can be used to recover and reuse waste products to reduce environmental damage and pollution In this two-volume set, Sustainable Resource Management: Technologies for Recovery and Reuse of Energy and Waste Materials delivers a compelling argument for the importance of the widespread adoption of a holistic approach to enhanced water, energy, and waste management practices. Increased population and economic growth, urbanization, and industrialization have put sustained pressure on the world’s environment, and this book demonstrates how to use organics, nutrients, and thermal heat to better manage wastewater and solid waste to deal with that reality. The book discusses basic scientific principles and recent technological advances in current strategies for resource recovery from waste products. It also presents solutions to pressing problems associated with energy production during waste management and treatment, as well as the health impacts created by improper waste disposal and pollution. Finally, the book discusses the potential and feasibility of turning waste products into resources. Readers will also enjoy: A thorough introduction and overview to resource recovery and reuse for sustainable futures An exploration of hydrothermal liquefaction of food waste, including the technology’s use as a potential resource recovery strategy A treatment of resource recovery and recycling from livestock manure, including the current state of the technology and future prospects and challenges A discussion of the removal and recovery of nutrients using low-cost adsorbents from single-component and multi-component adsorption systems Perfect for water and environmental chemists, engineers, biotechnologists, and food chemists, Sustainable Resource Management also belongs on the bookshelves of environmental officers and consultants, chemists in private industry, and graduate students taking programs in environmental engineering, ecology, or other sustainability related fields.
