Book excerpt: This information circular describes research the Bureau of Mines has conducted to improve technology for recovering precious metals from low-grade resources. Many of the reported findings are recent, and some of te work described is ongoing. Topics discussed include cyanidation of carbonaceous gold ores to enhance gold recovery, a new method for precipitating mercury during cyanide leaching of gold ores, a staged heap leaching process to generate suitable solutions for direct electrowinning of gold, the use of anion-exchange resins to recover gold from cyanide solutions, and precious metals recovery from electronic scrap.

Download or read book Novel Binders and Methods for Agglomeration of Ore written by S. K. Kawatra and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many metal extraction operations, such as leaching of copper, leaching of precious metals, and reduction of metal oxides to metal in high-temperature furnaces, require agglomeration of ore to ensure that reactive liquids or gases are evenly distributed throughout the ore being processed. Agglomeration of ore into coarse, porous masses achieves this even distribution of fluids by preventing fine particles from migrating and clogging the spaces and channels between the larger ore particles. Binders are critically necessary to produce agglomerates that will not break down during processing. However, for many important metal extraction processes there are no binders known that will work satisfactorily at a reasonable cost. A primary example of this is copper heap leaching, where there are no binders currently encountered in this acidic environment process. As a result, operators of many facilities see a large loss of process efficiency due to their inability to take advantage of agglomeration. The large quantities of ore that must be handled in metal extraction processes also means that the binder must be inexpensive and useful at low dosages to be economical. The acid-resistant binders and agglomeration procedures developed in this project will also be adapted for use in improving the energy efficiency and performance of a broad range of mineral agglomeration applications, particularly heap leaching. The active involvement of our industrial partners will help to ensure rapid commercialization of any agglomeration technologies developed by this project.

Download or read book Gold and Silver written by W. Joseph Schlitt and published by . This book was released on 1981 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The first chapter provides an overview of current leach operations while the next two examine the treatment of problem ores (carbonaceous, sulfidic and manganiferous). The next group of papers deals with heap leaching, an approach now gaining favor due to its low cost, rapid implementation and relative simplicity. These are followed by a paper on combined flotation and leaching. All these commercial leach operations utilize cyanide lixiviants and the next two chapters deal with treatment of such solutions to recover the values and avoid discharge of hazardous wastes. Use of thiourea as an alternative to cyanide is discussed in the following papers while assay methods and problems are covered in the twelfth paper. Substantive contributors by bankers, consultants and commodity traders have [also] been included in this volume."--Preface.
