| circuit board gold in electronics: Recovery and Refining of Precious Metals C.W. Ammen, 1997-07-31 This book is the product of 50+ years of hands-on physiochemical work with both ferrous and nonferrous metals and with the metallurgy of refining, extracting, and casting. Its purpose is to cover the various methods of recovery and refining of precious metals. Both primary sources (placer gold, black sand, and ores) and secondary sources (scrap jewelry, electronic scrap, old films, buffings, spent plating and stripping solutions, catalytic automobile converters, and old eyeglass frames) are covered. The information contained in this volume is very basic and is intended for hands-on application and use. It is for nonchemist and chemist alike. I will not discuss the mathematical formulas for the various chemical reactions that take place-I leave them to the reader who wants to increase his working knowledge and understanding of chemistry. There are many courses offered in chemistry and extractive metallurgy, as well as a number of books available for self-study. The purpose of this book is to teach you how to perform various extractive, refining, and testing operations on precious metals (in various forms and states), with a resulting end product. You will learn how to perform operations in assaying and extraction, qualitative analysis, quantitative analysis, testing, classifying, and concentration-some of a purely mechanical nature, some of a chemical nature. |
| circuit board gold in electronics: Digital Circuit Boards Ralph Morrison, 2012-05-29 A unique, practical approach to the design of high-speed digital circuit boards The demand for ever-faster digital circuit designs is beginning to render the circuit theory used by engineers ineffective. Digital Circuit Boards presents an alternative to the circuit theory approach, emphasizing energy flow rather than just signal interconnection to explain logic circuit behavior. The book shows how treating design in terms of transmission lines will ensure that the logic will function, addressing both storage and movement of electrical energy on these lines. It covers transmission lines in all forms to illustrate how trace geometry defines where the signals can travel, then goes on to examine transmission lines as energy sources, the true nature of decoupling, types of resonances, ground bounce, cross talk, and more. Providing designers with the tools they need to lay out digital circuit boards for fast logic and to get designs working the first time around, Digital Circuit Boards: Reviews in simple terms the basic physics necessary to understand fast logic design Debunks the idea that electrical conductors carry power and signals, showing that signal travels in the spaces, not the traces, of circuit boards Explains logic circuit behavior through real-time analysis involving the fields and waves that carry signal and energy Provides new information on how ground/power planes work Outlines a software program for solving energy flow in complex networks |

| circuit board gold in electronics: The Extractive Metallurgy of Gold John C. Yannopoulos, 2012-12-06 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. |

| circuit board gold in electronics: The Complete Technology Book on E-Waste Recycling (Printed Circuit Board, LCD, Cell Phone, Battery, Computers) NIIR Board of Consultants & Engineers, 2015-02-15 Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered as e-waste. With advancements in the electronic world almost occurring on a day-to-day basis and increased availability of products to the public, it is not surprising to see a staggering increase in the generation of electronic wastes over the past decade. The e-waste now represents the biggest and fastest growing manufacturing of wastes with as high as about 40 million tons a year at the global level. All these thing leads to increase in E-waste generation in the country. Electrical and electronic equipment contain different hazardous materials which are harmful to human health and the environment, if not disposed of carefully. Due to the lack of awareness for e-waste recycling in emerging economies, innovation hubs and centres of excellence have not yet been established. This has leads to the requirement of a proper disposal and recycling system so that environmental pollution and health hazard is reduced. We have tried to give information in this book which will help in minimizing this ever growing problem. Today the electronic waste recycling business is in all areas of the developed world a large and rapidly consolidating business.

| circuit board gold in electronics: High Tech Trash Elizabeth Grossman, 2006-05-06 The Digital Age was expected to usher in an era of clean production, an alternative to smokestack industries and their pollutants. But as environmental journalist Elizabeth Grossman reveals in this penetrating analysis of high tech manufacture and disposal, digital may be sleek, but it's anything but clean. Deep within every electronic device lie toxic materials that make up the bits and bytes, a complex thicket of lead, mercury, cadmium, plastics, and a host of other often harmful ingredients. High Tech Trash is a wake-up call to the importance of the e-waste issue and the health hazards involved. Americans alone own more than two billion pieces of high tech electronics and discard five to seven million tons each year. As a result, electronic waste already makes up more than two-thirds of the heavy metals and 40 percent of the lead found in our landfills. But the problem goes far beyond American shores, most tragically to the cities in China and India where shiploads of discarded electronics arrive daily. There, they are recycled-picked apart by hand, exposing thousands of workers and community residents to toxics. As Grossman notes, This is a story in which we all play a part, whether we know it or not. If you sit at a desk in an office, talk to friends on your cell phone, watch television, listen to music on headphones, are a child in Guangdong, or a native of the Arctic, you are part of this story. The answers lie in changing how we design, manufacture, and dispose of high tech electronics. Europe has led the way in regulating materials used in electronic devices and in e-waste recycling. But in the United States many have yet to recognize the persistent human health and environmental effects of the toxics in high tech devices. If Silent Spring brought national attention to the dangers of DDT and other pesticides, High Tech Trash could do the same for a new generation of technology's products. |

The authors discuss all the main stages of design - from the upper system level of the hierarchy (telecommunications system, 5G mobile communications) to the lower level of basic semiconductor elements, printed circuit boards. Since the developers of these devices in practice deal with distorted digital signals that are transmitted against a background of interference, the authors not only explain the physical nature of such effects, but also offer specific solutions as to how to avoid such parasitic effects, even at the design stage of high-speed devices. |

Georgalli, 2005-11-02 This book is a must for individuals and companies that have an interest in developing sustainable technology and systems in the complex 'Web of Metals' on a first principles, technological and economic basis, with a focus to the minerals, metals and product manufacturing industries. In this inter-, intra- and trans-disciplinary book the material/metal cycle will be central, addressing technology as the basis for achieving sustainability within the system of primary mineral and metal producing, and the consumer product material cycles, linked to nature's cycles. The following major topics (not exclusive) are discussed in a detail, which will satisfy company CEO's and students of environment, engineering, economics, and law alike: (i) industrial ecology, (ii) system engineering concepts, (iii) development of future breakthrough technology as well optimization of present technology, (iv) process fundamentals (e.g. thermodynamics, separation physics, transport processes etc.), (v) product manufacture and design (for recycling), (vi) environmental legislation and (vii) technology as a basis for achieving sustainability within our present society.The book discusses contentious issues such as the limits of recycling determined by physics, chemistry, economics and process technology, therefore providing the reader with a fundamental basis to understand and critically discuss the validity of environmental legislation. Furthermore, the 'Web of Metals' (i.e. the dynamic interconnection of metal and material cycles and product systems) will reveal that, if the application of environmental evaluation techniques such as material flow analysis, life cycle assessment etc. are not carried out on a sufficient theoretical basis, technological and economic understanding, analyses could lead to erroneous and in the end environmentally harmful conclusions.The book is illustrated with many industrial examples embracing car and electronic consumer goods manufacturing and recycling, and the production and recycling of all major metals (e.g. steel, aluminium, copper, zinc, lead, magnesium, PGM's and PM's) and to an extent plastics. A complete section of the book is devoted to the recycling of light metals. Numerous colour figures and photos, plant and reactor data as well as software and computer models (running under Matlab's Simulink® and AMPL® as well as tools based on neural net technology (CSenseTM) are provided to give the reader the opportunity to investigate the various topics addressed in this book at various levels of depth and theoretical sophistication, providing a wealth of information, share-data and industrial know-how.Finally, the book philosophically discusses how to harmonize the resource, life and technological cycles depicted by the figure on the cover to make a contribution to the sustainable use of resources and products.* Material and Metal Ecology and the various modelling aspects to quantify this * System modelling of recycling systems with applications in the automotive and consumergoods sector* Metallurgical metal recycling with applications in aluminium, supplemented with various modelling examples from thermodynamics, exergy, neural nets to CFD |
| circuit board gold in electronics: Reverse logistics of waste electrical and electronic equipment and environmental sustainability Uanderson Rebula de Oliveira, 2020-06-03 The sale of Electrical and Electronic Equipment (EEE) is growing worldwide due to technological innovations and the speed with which they become obsolete, which increases the production of a solid residue called Waste Electrical and Electronic Equipment (WEEE), or e-Waste. WEEE is a relevant problem, as it contains several toxic substances capable of harming the environment and human health. This is why a proper environmental management is required. After the creation of the National Policy on Solid Waste (PNRS) in Brazil - Law No. 12.305, of August 2, 2010, manufacturers, importers, distributors, and traders have become responsible for implementing Reverse Logistics (RL) systems, which aim at the return of products after use by the consumer. Although the electronics industry is concerned about the RL of its products, RL of WEEE is not a subject widely addressed within Brazil or internationally. In fact, e-waste is a new subject in the world literature. This book aims to identify how WEEE management can contribute to the improvement of the EEE supply chain performance in Brazil, at an environmental sustainability point of view. Therefore, we identify: The global and Brazilian background, overview, and perspectives to improving solid waste and WEEE management at an environmental sustainability point of view; Brazilian legislation and practices; international legislation and good practices in WEEE management, which suggest improvements to the WEEE management in Brazil; and good practices in using product identification technologies, such as Radio Frequency Identification (RFID) in e-waste reverse logistics systems, such as the renowned Hewlett-Packard (HP) Smartwaste Project. |

| circuit board gold in electronics: Manufacturing Technology in the Electronics Industry P. Edwards, 2012-12-06 The sequence of events which led to the writing of this book started at a seminar on Manufacturing Technology in the Electronics Industry given by the Institution of Production Engineers in 1987. The seminar identified that the field of manufacturing engineering for the electronics industry was effectively missing from the vast majority of production engineering degree courses. The reason for this was that production engineering departments typically spring from mechanical engineering departments. This leads to a mechanical bias in the practical aspects of such courses. The consequence of this was that electronics companies could not recruit graduates with both relevant production engineering and electronic engineering backgrounds. This necessitated either recruiting production engineering graduates and giving them the necessary electronic engineering training, or giving production engineering training to electronic engineering graduates. A consequence of the lack of courses in a subject is that there is also a lack of relevant textbooks in the area, as most textbooks are intended to tie into courses. In the field of manufacturing technology for the electronics industry, existing textbooks tend to be highly specialized and mainly concerned with the fabrication of semiconductor devices. |
