“Process and Environmental Chemistry of Cyanidation” is the first comprehensive publication dealing exclusively with the chemistry of gold dissolution. Holding a Ph.D. in emistry and 15 years of experience in chemical consulting in the gold mining industry, the author focuses on the stepchild of the gold metallurgy, the cyanidation chemistry.
The book provides a theoretical approach for research and university as well as a detailed description of the practical aspects occurring at a gold extraction plant and in water treatment facilities. This publication is intended for all professionals in the gold and silver mining industry, but also useful to the copper industry. As main focus this book should be used as a guideline for plant metallurgists to solve problems in process chemistry or in effluent treatment. The reader will be able to trace any problem or question back to its chemical origin, which makes this publication also for interest for scientists and process engineers in research, design, production and consulting. “Analytical Methods for cyanide Determination” for the day-to-day analyses at a cyanidation plant and a chapter on “Process Chemistry” are scheduled to help the mine operator to apply cyanide chemistry at the plant side to optimize gold extraction and cyanide consumption. As cyanide often is considered as an environmental hazard, this publication also discusses “Alternative Lixiviants” comparing performance and toxicity with cyanidation.
“The Fate of Cyanide in the Environment” is shown to be no secret anymore, when looking into the chemistry of naturally occurring attenuation mechanisms, which explain what happens to the cyanide after the gold extraction is completed. The publication starts with a chapter about the gold mineralogy to supply the background needed to understand the mineralogical and chemical surrounding of the gold particles in the ore as a basis for the chemistry occurring in the cyanidation process. The “Principles of Cyanidation” describes the theoretical background of cyanidation, summarizing the general chemistry involved, which includes e.g. the cyanidation chemistry of base metals and the chemistry of thiocyanate formation being considered the main reaction in cyanidation. A chapter on the “Toxicity of Cyanide” shows the action of cyanide in human, animal and plant metabolism and discusses toxicity levels. The publication closes with a section on “Cyanide Recycling and Detoxification” to illustrate and compare the different methods on the market. It is especially shown which detoxification process should be applied for what problem and when cyanide recycling makes sense.
