Book excerpt: This report provides practical, timely information on methods and equipment used in placer gold recovery. Included is detailed information on equipment, practices, recovery factors, efficiency, design, and, where available, costs. Selected gold recovery operations are described in detail. In addition, the reported efficiency and reliability of various types of equipment used today is presented. One notable method not described is the cyanide process, the recovery of gold through leaching with cyanide, a hazardous substance that must be handled with great care. The information presented herein applies to small as well as large placer mining operations. Recreational and independent miners will find information on available equipment and designs with some suggestions for improving recovery. Those intending to mine small to medium-sized placer deposits will find detailed descriptions of suitable equipment and recovery methods.

Available in PDF, EPUB and Kindle. Book excerpt: Gravity-separation tests on backfill material finer than 1 mm showed that up to 60 per cent of the gold could be recovered by a spiral concentrate of 20 per cent by mass of the feed. The highest recovery was obtained at a pulp density of 30 per cent solids. The use of a thicker pulp, containing 50 per cent solids, decreased the gold recovery by about 5 per cent. Treatment of deslimed material on the spiral did not increase the recovery. A further 8 per cent of the gold was recovered from the material coarser than 1 mm crushed to finer than 600 micrometres and upgraded on the spiral. Because this coarse material improves the stability of the backfill, it is suggested that it could be jigged in an attempt to recover some gold without reducing its particle size. In January 1986, the capital cost of a plant to treat rod-mill discharge at a rate of 15 t/h was about R30 000, excluding tax and installation costs. The operating costs would be minimal.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This volume is based on the proceedings of the "NATO Advanced study Institute on Mineral Processing Design" held in Bursa-Turkey on August 24-31, 1984. The institute was organized by Professor B. Yarar of the Colorado School of Mines, Golden, Colorado, 80401, USA, Professor G. Ozbayoghu and Professor Z. M. Dogan of METU-Ankara, Turkey, who was the director. The purpose of the institute was to provide an international forum on the subject and update the information available. Participants were from Turkey, England, Greece, Spain, Portugal, Belgium, Canada, and the USA. Besides authors contributing to this volume, presentations were also made by Drs. Yarar, Raghavan, Schurger, and Mr. Kelland. Many assistants and colleagues helped. They are gratefully acknowledged. Acknowledgment is also owed to Drs. Ek, de Kuyper, and Tolun. Dr. Gfilhan Ozbayoglu, and Mr. S. Ozbayoglu were particularly helpful in the overall organization and hosting of many international guests. We owe them special thanks. NATO, Scientific Affairs Division, is gratefully acknowledged for the grant which made this activity possible. Z. M. Dogan B.

A procedure for conductiqg mineralogical studies in conjunction with ore dressing was, therefore, developed. The procedure includes characterizing the ore and analysing the mill products.

Available in PDF, EPUB and Kindle. Book excerpt: For over the past 500 years, most world education systems continue to this day to teach little-to-none of Flat Earth history and Cosmology connecting to this rich history of all our common pasts. Why would they not want us to know the narrative of our existence where the Sun, the Moon, and the Stars were placed in the sky above to help guide and assist us? Why is there this conspicuously massive omission in taught history of The Enclosed Cosmological Model? If it is archaic history, then teach it as such. But, it has been completely scrubbed from the historical record, apart from being mocked and ridiculed by all institutions of both lower and higher learning. Ask yourself, why? Thousands of classes on Greek Mythology are readily available to anyone in every country. You can learn about Zeus's Lightning Bolts, the One-Eyed Cyclops, Medusa's snake filled hair, and just about any other imaginary and mythological creature and idea possible, but never about The Flat Earth Model and the mathematical mechanics behind it. If it's a crazy myth, then simply throw it into Mythology 101 at your local college. But no, this never happens. Again, why? If it is as crazy as Greek Mythology, then just say so and teach it. But no, this does not happen. Contrarily, what would anyone gain by creating a Heliocentric myth that states we should feel insignificant, small, and just one of billions, and billions, and billions of other planets, stars, and potential forms of life? The answer is short: Power. If you were in power, would you want the minions one day to take over your power base that has been created over hundreds, if not thousands of years? Would it not benefit you, as tyrant, to teach a version of The Cosmos which convinces all who are under your subjugation to feel powerless, insignificant, and meaningless as they drift in a vast, chaotic, and hostile Cosmos, where their only hope of survival was to obey you and submit to your edicts and laws? The fact is that the self-appointed powers in charge of this world employ propaganda, monetary policy, organized religion, and infotainment to mesmerized the mases. They wish to keep us fully disempowered as to our highest potential by severing us from any knowledge that we were literally created to exits at the epicenter of God's Creation. From Copernicus, all the way to the creation of The Big Bang Theory by Jesuit/Catholic priest, Father George Lemaitre, The Vatican and the Society of Jesus (Jesuits) have had, and still to this day, have a vast and sweeping influence in all things related to Astronomy, Astrophysics, and space observation. In fact, it was Father George Lamaitre, not Albert Einstein, who in 1922 created the scientific "provable" science behind our current Pantheistic Evolutionary explanation of how our world came to be. Vatican control exists at the center of the spider's web, without a doubt. The epistemological cartels behind the idea of Gravity, such as The Royal Society of London, as well as other The Masonic fraternities, have a vested interest in Gravity existing as the sole foundational connective tissue and explanation for The Heliocentric Theory, The Big Bang Theory, Evolutionary Theory, as well as their agenda for the certain possibility of alien life All their occult science ideologies rest upon the idea that Gravity is real. And so, all institutions of higher learning, private businesses, think tanks, corporations, Hollywood, NASA, etc... under the influence and pressure of epistemological cartels, such as The Royal Society of London, are only funded if they assert that Gravity is real for the benefit of the agendas of The Scientific Autocracy that funds them. And The Myth of Gravity explains the backstory behind this Masonic Heliocentric deception, as well as the mathematical trickery involved in perpetrating it.
