This book was released on 1966 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of both the writer's visit to the Kalgoorlie goldfield in Western Australia and the testwork conducted in the Government Metallurgical Laboratory on refractory gold ores, several recommendations have been made in this report for future work on the refractory gold ores from the Barberton goldfield. The conclusion has been drawn that it is unlikely that a treatment method, for oxidation of auriferous sulphide concentrates, economically superior to roasting will be developed. Consequently, eight recommendations, oriented towards the possibility of increasing the income of the Barberton mines, have been made. These recommendations, which aim at reducing the gold content of all waste material discarded from the reduction works and developing the recovery of saleable material other than gold, are as follows: 1. That cyanidation of the flotation concentrate be investigated with special reference to reducing the gold value of the calcine cyanidation residue and to the recovery of silver. 2. That the method of roasting be assessed with a view to improving, if warranted, control over the chemical reactions involved during roasting. 3. That testwork be continued on the recovery of gold from the calcine cyanidation residue. 4. That methods for reducing the gold content of the flotation tailings be investigated. 5. That the recovery of arsenic and gold from the flue gases be investigated. 6. That the recovery of elemental sulphur, or alternatively, the manufacture of sulphuric acid be investigated. 7. That the recovery of gold from the carbonaceous scum from the Sheba mine be investigated. 8. That the pressure oxidation of the auriferous sulphide concentrate be investigated.

Book excerpt: The eight articles first appeared as volume 6 (no date) of Mineral processing and extractive metallurgy review. They review new methods of recovery for gold, and to some extent, silver, focus on the particular challenges of extraction from carbonaceous ores and from various sulfide-bearing ore, and the treatment of refractory gold ore, and discuss high-temperature and biological oxidation, high- temperature chlorination, and removing metals from leach liquor.

Available in PDF, EPUB and Kindle. Book excerpt: The results of cyanidation experiments on a number of gold ores and calcined gold concentrates that contained sulphidic and arsenical minerals or their oxidation products were analysed. It was found that the results were not entirely compatible with previously postulated theories on the refractoriness of such ores. It has been assumed in the past that gold should be recoverable by the cyanidation process unless the surface of the gold particles is not exposed to attack or unless the nature of the ore minerals is such that they react with the cyanide or oxygen in the solution, leaving insufficient quantities of reagents for the dissolution of the gold. Experimental work carried out on pure gold discs has shown conclusively that the dissolution of gold in cyanide solution can be inhibited by the presence of iron sulphide and arsenide minerals and their oxidation products in a manner that can be accounted for only by the formation of strongly adherent films of some as yet unknown species on the surface of the gold. The effects of alkalinity, cyanide concentration, oxygen concentration, rate of agitation, and temperature of solution on the rate of the dissolution of gold in the presence of various minerals were investigated.

This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial leaching for the recovery of refractory gold from sulphide concentrates depends largely upon the mineralogical suitability of the substrate. The susceptibility of sulphide minerals to bio-oxidation is discussed in terms of their trace-element chemistry, crystal structure, physical form, and mineral intergrowths. A mathematical model is derived to describe the relationship between the breakdown of sulphide and the release of gold. The rate of release of gold can be considerably enhanced where the precious metal is concentrated in structural defects in the sulphides, because these defects are sites of preferred bacterial corrosion.
