This course provides a non-technical introduction to the use and management of cyanide on a global basis. The course is designed to provide the global picture of cyanide use and how it compares with other chemicals used around the world. Cyanide is used in gold mining operations, however, there is much confusion regarding the real impact of cyanide use in mining. This course attempts to dispel the myths and mysteries surrounding cyanide and provide reliable facts and figures. The course begins with an examination of the production, use, treatment, and transportation of cyanide worldwide, followed by discussions of its technical properties, risks, and management. Subsequent courses in the Cyanide Management in Mining series detail specific technical aspects highlighted in this introductory course.

Acid Rock Drainage (ARD) Prediction provides an introductory course and application reference for students, technicians, and practicing geochemists, geoscientists and other professionals who desire a solid grounding on the subject. The course provides sufficient knowledge and background to allow useful application of the presented information toward site assessment with regard to the evaluation of acid generation potential. By design, Acid Rock Drainage Prediction emphasizes the practical application of the concepts presented and limits the presentation of theory to the level required for a basic understanding of the topic. The aim of this course is to provide an overview of the concepts underlying acid rock drainage prediction and to act as a resource for practitioners to become more familiar with or reaquaint themselves with the topic. For those who require a specialized theoretical background on the topic, ARD Prediction provides an exhaustive list of technical references. The companion textbook to this course which contains some of the course text and has additional references should be read in conjunction with this course: Acid Mine Drainage, Rock Drainage and Acid Sulfate Soils, causes, assessment, prediction, prevention and remediation, edited by James A Jacobs, Jay H. Lehr, Stephen M. Testa, John Wiley & Sons, 2014. Principal topics covered by the course include: Chemistry, Mechanisms and Sources Site Assessment and Sampling Mineralogical and Geochemical Interpretation Static Laboratory Tests and Interpretation Kinetic Laboratory Tests and Interpretation Waste Material Management Case Studies in ARD Prediction Authors Chris Mills MSc P.Eng (Author) Bruce Downing MSc P.Geo (Co-Author) Dr. Andy Robertson P.Eng (Co-Author)   Duration: 33 Hours Access: 90 Days Category: Environment Level: Specialize Version Date: December 15, 2014   ​Need to train a team?

This is the first course in the six-course Cyanide Management in Mining series. This course assumes knowledge of environmental engineering or mineral processing. The chemistry of cyanide solutions is unique with its ability to dissolve gold and silver. Cyanide is highly selective with respect to combining with gold and silver; in solution it forms complexes with other metals, such as mercury, zinc, copper, iron, and nickel. The formation of these other metal complexes partially account for the consumption of cyanide in gold extraction circuits and generate solutions that can be difficult to treat and analyze. Although chemical replacements for cyanide have been investigated for decades, it remains the exclusive extraction reagent or lixiviant of choice for over 90% of the gold recovered. This is due to a combination of availability, effectiveness, economics, and an ability to use and manage cyanide with acceptable risk to humans and the environment. Cyanide Management in Mining Series The Cyanide Management in Mining course series provides the learner with the necessary background for developing a cyanide management plan that meets the unique requirements of each operating mine. Due to environmental risks, a cyanide management plan is of critical importance to a mining operation. The lack of such a plan, in some cases, has contributed to adverse environmental incidents involving cyanide. The series consists of the following courses. Chemistry of Free and Complexed Cyanide Analysis of Cyanides Geochemical Properties and Environmental Fate of Cyanide Toxicity and Environmental Properties of Cyanide Water Management and Discharge Strategies Treatment Technologies for Cyanide and Related Compounds Authors Dr. Terry Mudder   Duration 3 Hours Access 90 Days Category Environment Level Specialize Version Date August 17, 2018 ​Need to train a team?

The cyanidation process for the extraction of gold and silver from ore has been employed since 1898 when it was first used in New Zealand and Africa and soon after in the United States. It is a very efficient process capable of extracting gold in amounts of less than one percent of an ounce from a ton of rock with over 90% efficiency. Because of the environmental risks, a cyanide management plan is of critical importance to a mining operation. The lack of such a plan, in some cases, has contributed to adverse environmental incidents involving cyanide. The United Nations Environment Programme (UNEP) is developing an international code for the management of cyanide. Implementation and adherence to this code, augmented by experienced scientific and engineering judgment, will help reduce both the number and severity of environmental incidents involving cyanide. The "Cyanide Management in Mining" courses attempt to provide the user with the necessary background for development of a cyanide management plan that meets the unique requirements of each operating mine. The full complement of courses in the series includes: Chemistry of Free and Complexed Cyanide Analysis of Cyanides Geochemical Properties and Environmental Fate of Cyanide Toxicity and Environmental Properties of Cyanide Water Management and Discharge Strategies Treatment Technologies for Cyanide and Related Compounds "Analysis of Cyanides" is the second in the series of six courses. This course covers the methods available for measurement and analysis of different categories of cyanide, and discusses the advantages, disadvantages and problems associated with them. It also covers sources of analytical interference in cyanide analysis, variability and accuracy, and measurement of low levels of cyanide in the environment. This course comprises 10 viewing sessions, each of 30 - 60 minutes duration, plus supporting figures, tables and references, and two interactive reviews that confirm achievement of the learning objectives Authors Dr. Terry Mudder   Duration 8 Hours Access 90 Days Category Environment Level Specialize Version Date July 10, 2006 ​Need to train a team?
