All new revised 2023 edition! A daily growing number of people have access to sources of scrap with precious content. Knowing the composition of this material can increase it ́s value tremendously for the owner. Many types of gold scrap is available for free, so that the initial risk for start-ups is minimal. Even just collecting precious scrap like electronic waste is no waste of time, because it can be resold under today ́s market conditions. It is hard to believe, that there still could be individuals or organisations out there, that ship and unload their e-waste in far away countries and leave all those values behind. The truth rather is, that the race for the recovery of precious metals in urban enviroments has begun. This new goldrush won ́t last forever, but the tidal wave that it will cause, will be as big as the wave that once pumped up the electronic market who produced these items. What goes up, must come down. The new gold rush doesn ́t take place in remote places, it will take place in urban areas, where most valuable scrap is concentrated. That offers new opportunities for smart people in the years to come. This book gives a compact overview of the most common sources of precious metals in an urban enviroment, how they yield and how to proceed after collecting them. Mechanical and chemical procedures are presented without expecting too much foreknowledge. It further discusses related social and financial issues.
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.
In 2008,history was made when the price of gold exceeded the historic "Boom" of 1980.While people missed out,Richard Frankel was smack dab in the middle of it.He knew then that this would be the only business for him. When history repeated itself,he decided to re-release his manual with nuances to prepare his readers. No trade secrets are left out.Basic and vital fundamentals are discussed. Testing gold,silver,and platinum as well as diamonds and coins are discussed.Lessons on how to weigh precious metals,determine value, and sell according to the metals market.This manual will even educate you on how to sell resalable jewelry that was purchased as scrap.Above all,how to find prospects.Advertising on a shoe string budget and ways to diversify during slow peaks are discussed at length.This manual is not limited to the gold business since the underlying current is about believing in yourself.This just may be an important tool to own for anyone who wishes to get ahead no matter what business you choose to be in.
This is a book designed for the home chemist. Are you tired of big refineries taking half of your metals? Then the processes described in this book are for you. You will learn detailed ways to recover and refine your own precious metals at home.
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.

In 1945, US intelligence officers in Manila discovered that the Japanese had hidden large quantities of gold bullion and other looted treasure in the Philippines. President Truman decided to recover the gold but to keep its riches secret. These, combined with Japanese treasure recovered during the US occupation, and with recovered Nazi loot, would create a worldwide American political action fund to fight communism. This 'Black Gold' gave Washington virtually limitless, unaccountable funds, providing an asset base to reinforce the treasuries of America's allies, to bribe political and military leaders, and to manipulate elections in foreign countries for more than fifty years.
