| extract gold from 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. |

| extract gold from electronics: Waste Kate O'Neill, 2019-09-04 Waste is one of the planet’s last great resource frontiers. From furniture made from up-cycled wood to gold extracted from computer circuit boards, artisans and multinational corporations alike are finding ways to profit from waste while diverting materials from overcrowded landfills. Yet beyond these benefits, this “new” resource still poses serious risks to human health and the environment. In this unique book, Kate O’Neill traces the emergence of the global political economy of wastes over the past two decades. She explains how the emergence of waste governance initiatives and mechanisms can help us deal with both the risks and the opportunities associated with the hundreds of millions – possibly billions – of tons of waste we generate each year. Drawing on a range of fascinating case studies to develop her arguments, including China’s role as the primary recipient of recyclable plastics and scrap paper from the Western world, “Zero-Waste” initiatives, the emergence of transnational waste-pickers’ alliances, and alternatives for managing growing volumes of electronic and food wastes, O’Neill shows how waste can be a risk, a resource, and even a livelihood, with implications for governance at local, national, and global levels. |

| extract gold from 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. |
| extract gold from electronics: The Great Gold Swindle of Lubec, Maine Ronald Pesha, 2013-04-16 In 1897, a stranger named Reverend Prescott Jernegan arrived in Lubec and made a bold claim: he could extract gold from seawater. To do so, he used so-called accumulators of electrically charged rods in iron pots. Fooling many, he actually hid the gold beneath a wharf in the Bay of Fundy during the night. He and his accomplice, Charles Fisher, preached with fervent enthusiasm as they built their factory and encouraged inspections, which reversed doubters to greedy high-stakes investors. Hundreds of laborers accelerated factory expansion until July 1897, when Jernegan and Fisher fled. Although residents of Lubec attempted civil and criminal action, both men relocated, and fantasies of gold wealth flowed away. Relive the excitement, disappointment and anger of turn-of-the-century Mainers in this collection of accounts about the Lubec gold hoax. |
| extract gold from electronics: Investing in Gold: The Essential Safe Haven Investment for Every Portfolio Jonathan Spall, 2008-12-01 Can you afford not to buy gold? As many investors know, gold is a “safe-haven” asset that can actually increase in value during stock market slides and times of recession. But what else do you really know about this commodity? Are you taking full advantage of it? Do you know how to work it into your overall investment strategy? This detailed tutorial provides you with a comprehensive understanding of gold, from mine to market. Jonathan Spall, a 25-year veteran of the metals market, explains everything you'll need to know for making gold a profitable part of your investment strategy. Investing in Gold gives you an inside look at how the precious metal is mined, refined, traded, and priced, along with valuable insight into gold's unique position in the marketplace. Spall explores such topics as: Simple and complex gold trading processes The pivotal role central banks play in the gold market Gold exchange traded funds (ETFs) How spot gold is traded Why gold mining companies have traditionally hedged and why they no longer do so Strategies for investing in the retail market Spall provides an extensive glossary of terms you'll need to know, and he debunks various myths regarding this market, including the Fed's supposed scheme to keep gold prices artificially low during the 1990s. The effects of global economic growth, the weakened dollar, the credit crunch, and the recent creation of enormous funds each affect the gold market; put them together and they add up to potential profits gold investors have never before dreamed of. Gold is a surprisingly small market. When you learn how to navigate it, the potential for excellent rewards becomes evident. |
| extract gold from electronics: Digital Rubbish Jennifer Gabrys, 2013-04-26 This is a study of the material life of information and its devices; of electronic waste in its physical and electronic incarnations; a cultural and material mapping of the spaces where electronics in the form of both hardware and information accumulate, break down, or are stowed away. Where other studies have addressed digital technology through a focus on its immateriality or virtual qualities, Gabrys traces the material, spatial, cultural and political infrastructures that enable the emergence and dissolution of these technologies. In the course of her book, she explores five interrelated spaces where electronics fall apart: from Silicon Valley to Nasdaq, from containers bound for China to museums and archives that preserve obsolete electronics as cultural artifacts, to the landfill as material repository. Digital Rubbish: A Natural History of Electronics describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys draws together the far-reaching material and cultural processes that enable the making and breaking of these technologies. |

| extract gold from electronics: Op Amps for Everyone Ron Mancini, 2003 The operational amplifier (op amp) is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits. |

| extract gold from electronics: Biomining Douglas E. Rawlings, 2013-03-09 Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of ores because as they oxidize the ore, they open up its structure, thereby allowing a gold-solubilizing agent such as cyanide to penetrate the ore. The book describes several industrial bioleaching and biooxidation processes as well as the underlying theory and biology of the microbes involved. |

Dr. Frances Cress Welsing first told us the chemical melanin is produced through a process known as melanogenesis upon introduction of the chemical tyrosine to the enzyme tyrosinase. Melanin is found in such diverse places as bird feathers, animal fur, reptile scales, microorganisms, cephalopod ink, mushrooms and even fossils. Additionally, melanin is found in the hair, skin and eyes of people. Melanin is subjected to intense scientific scrutiny. Nevertheless, the highly educated people studying it had no idea melanin is worth more than gold. In June 2014 a post to the Keyamsha the Awakening blog openly declared melanin was worth $353 a gram and $300 a gram more than gold. Shortly afterwards, hoaxers began bombarding the blog with comments claiming melanin thieves were harvesting melanin from Black people. The hoax was easily falsified. The hoaxers made certain to never mention the company selling melanin extracted from the ink of sepia officinalis, the common cuttlefish. During the intervening years the melanin thieves hoaxers persisted in their efforts. In March 2017, the melanin thieves hoaxers launched a Melanin Twitter bomb involving the dollar value of melanin after publicity of black women and girls missing in Washington, D.C. was released. Their actions exposed a frailty in their psyche. They also reveal it is possible to wipe out false information involving melanin and take the melanin challenged inferiority complex (aka racism/white supremacy) along for the ride. It then became clear the time had come to enter the fray and dispel the myths about melanin. This book completely obliterates the false narrative of melanin. Perceiving facts from a melanin-centered perspective bestows upon us an expanded awareness of the world and our place in it. It helps provide the average person a means to immerse themselves in melaninology and emerge a melaninologist. Essentially, we get to know ourselves. To date no other path for the public to independently verify, or falsify, outlandish claims regarding melanin being worth more than gold on their own without any guru to guide them have been made available. At this writing, melanin is worth over $395 a gram more than gold. In ancient Kemet (misnomered Egypt) such words were known as hekau or words of power with the ability to heal. For nearly one-hundred years, since August 13, 1920, melanin put the B in R.B.G. and the Black in Red, Black and Green as the flag of Africans, at home and abroad.. Those are hekau, also. Our Blood, Our Melanin and Africa unites us. More hekau. The Afro, official currency of the United States of Africa, also known as the African Union, is worth $2.22. We are swathed in hekau to such an extent Mchakato Wa Uponyaji (Swahili for the process of healing) has begun. All of which indicates we are living in a new era: the era when all the generations of man can be called blessed on a planet that works for everyone. This era demands we convene the Ubuntu Convention. That plebiscite sets the stage for drafting the Ubuntu Declaration. In emulating the success of the August 1920 Universal Negro Improvement Association convention, we deliberately create the world where we intend to live. The revival of the U.N.I.A. with 12 million dues-paying card-carrying members positions the organization to have a treasury flush with over $400 million liquid.

| extract gold from electronics: Chemistry of Gold Extraction Mineekshi Awasthi, 2015-03 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. |
