Available in PDF, EPUB and Kindle. Book excerpt: The gold processing industry is experiencing change. As free-milling and oxide ores become depleted, more complex polymetallic and refractory ores are being processed, coupled with increasing pressure for stricter environmental compliance. Recent years have also seen a steady reduction in mineral processing and metallurgy graduates and a gradual loss of older operating experience. A contribution to documenting current and future best practice in gold ore processing seems timely.The focus of this volume is on advances in current gold plant operation, from conception to closure; chapters also cover innovations at the bench and pilot-scale level that would be expected to find commercial application at some stage. Sufficient coverage is also given to the chemistry and engineering aspects. The general principle behind the structure of the volume is that of flowsheeting based on unit operations and applied to a mineralogical classification of gold ore types. From concept to closure, this book covers all unit operations, mineralogies and processes that are relevant to dealing with today's complex orebodies.Practical experience is vital to the successful development, operation and closure of any operation. The 42 chapters have been contributed by a total of 66 authors and co-authors who are experts from countries spanning the globe, and representing exhaustive practical knowledge covering many disciplines relevant to gold processing.* Current best practice as elucidated by a select panel of experts in the field* Innovations at the bench and pilot-scale level that would be expected to find commercial application at some stage* Mineralogical-based approach to flowsheeting

This book was released on 1972 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasingly stringent stream discharge regulations have prompted an assessment of the current technology available for application to the metal finishing waste treatment problem, specifically in regard to smaller operations. Experimental laboratory and bench scale studies were then conducted on several unconventional wastewater treatment methods, including ion flotation, activated carbon adsorption, acidification volatilization, and solvent extraction. A demonstration pilot plant study was also conducted on the activated carbon process employing actual rinse waters from a zinc cyanide plating operation. The pilot scale activated carbon system was operated at 99% efficiency of cyanide removal, while providing for the complete recovery and regeneration of copper. Cost estimates for carbon sorption process are given.

Download or read book Cyanide in Water and Soil written by David A. Dzombak and published by CRC Press. This book was released on 2005-12-09 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of cyanide is a significant issue in industrial and municipal wastewater treatment and management, in remediation of former manufactured gas plant sites and aluminum production waste disposal sites, in treatment and management of residuals from hydrometallurgical gold mining, and in other industrial operations in which cyanide-bearing wastes were produced. The complexity of the chemistry and toxicology of cyanide and the risk it poses in different environmental contexts make its management and remediation extremely challenging. Cyanide in Water and Soil is the first book to present the state-of-the-art in managing cyanide across a wide range of industrial and environmental contexts. The book brings together current knowledge and information about cyanide release to and behavior in the environment, and explores how to control or remediate these releases. No other broad-based examination of this topic exists. Exploring the anthropogenic and natural sources of cyanide in the environment, the authors address the full range of issues pertaining to cyanide fate, transport, treatment, and toxicity in water and soil as well as approaches currently used in risk assessment and management. They have developed a careful balance of depth and scope of coverage, providing current references that help readers learn more about topics of particular interest. An array of technologies is available for the treatment of cyanide in surface water and groundwater, wastewaters, and contaminated soils and sludges. These technologies span the gamut of biological, chemical, electrolytic, physical, and thermal treatment processing. Presenting examples of applications of the technologies employed most commonly in municipal and industrial settings, the book is a useful reference tool for engineers, scientists, practitioners, and researchers in academia, industrial organizations, government, and engineering and science consulting firms.

Download or read book Water Quality written by Hlanganani Tutu and published by BoD – Books on Demand. This book was released on 2017-01-18 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: As concerns increase over the scarcity of water resources and the role of anthropogenic activities, water quality is evermore important. Activities ranging from agriculture to mining have had a bearing on the quality of water that they impact. Several studies assessing such impacts have been conducted at local and global scales over the years. This book, consisting of contributions by authors in various water-related fields, delves into some approaches that are used to understand and/or to improve water quality, and these include assessment of water chemistry, biomonitoring, modelling and water treatment. This book will be useful to environmental scientists, water professionals, researchers, academics and students.

Download or read book Treatment of Complex Cyanide Compounds for Reuse Or Disposal written by Thomas N. Hendrickson and published by . This book was released on 1973 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex cyanides (forro- and forricyanide) in industrial waste water effluents impose a direct threat upon the environment. Methods to recover or destroy these compounds were evaluated in laboratory studies. The techniques tested include electrolysis, ozonation, chlorination and heavy metal ion precipitation. The study was conducted to determine the feasibility of using one or more of these methods to reduce the concentration of ferricyanide in both concentrated (10,000 to 100,000 mg/1) and dilute (10 to 100 mg/1) waste effluents. Numerous analytical procedures were developed to enhance the accuracy of sample analysis over the concentration range studied. Ferrocyanide can be oxidized to ferricyanide in overflow photographic color process bleaches using either electrolysis or ozone and the waste bleach recirculated for reuse in the process. Dilute concentrations of ferricyanide can be destroyed using ozone or chlorine under proper conditions of temperature, pH, and catalyst addition. A cost analysis is included for all methods that were judged acceptable for commercial demonstration. Cost data for each procedure is based upon an "average combined" photographic processor as defined in the report. This report was submitted in fulfillment of Project 12120 ERF, under the partial sponsorship of the U.S. Environmental Protection Agency.
