Course Summary


This short course will augment the technical skills of the participants regarding all facets of cyanide in its relationship to the environment, humans, and mining. At the same time the course will provide a knowledge base of sufficient depth to aid those at either operations and/or corporate offices in development of sound cyanide management plans and those contemplating participation in the International Cyanide Management Code for Gold Mining Operations.

The course will aid those involved in the permitting, design and operation facets of the mining industry to ask the appropriate questions and to make justifiable and practical decisions. This short course is supplemented by seven online courses as well as an electronic bookstore from which dozens of documents can be purchased related to environmental aspects and metallurgical use of cyanide.


The increased awareness of the environmental implications associated with cyanidation has led to a tremendous increase in the knowledge of chemistry, analysis, toxicity and treatment of its process solutions. These four aspects of the cyanidation process are intimately related, with the treatment of cyanidation solutions forming the visible bridge between the mining operation and the receiving system or environments. There is sufficient detail and depth of expertise, experience and information to begin to quantify the impacts of cyanidation and to provide permanent, reliable and environmentally acceptable solutions to long-standing concerns.

In the year 2000, a release of cyanide from a tailings dam in Romania caused a global reaction and as a result the International Cyanide Management Institute was created along with the first industry-wide Cyanide Code for managing its use at gold mining operations. This two day course provides a background of technical information to supplement those manufacturing, transporting, using, regulating, and researching cyanide not only in the mining industry but also industries such as electroplating.

The chemistry of the cyanidation process is well defined, but its impacts on the characteristics of mine waters and the costs of water treatment have often been underestimated during the initial stages of mine development. Today, however, the mining industry is well aware of the consequences of inadequate environmental management and has invested hundreds of millions of dollars in the development of state-of-the-art tailings disposal and water treatment systems.

The analysis of cyanidation process waters has evolved from the free cyanide titration with silver nitrate to the speciation of individual metal cyanide complexes in the part per billion range using specialized ion chromatography methods. Although many analytical methods are available, only a few are capable of producing reliable and accurate data. It is necessary to focus upon and improve existing methodology, while appropriately using analytical methods currently in wide usage.

The toxicity of cyanidation solutions is complex, as it involves not only individual compounds, but combinations of compounds which exhibit characteristics much different than any of the individual components. There is now sufficient toxicological information concerning cyanidation process solutions to quantify and calculate acceptable discharge limitations on a site-by-site basis. This approach requires the practical application of both laboratory and field data to provide acceptable levels of environmental protection.

The chemistry, analysis and toxicity of cyanidation process solutions are combined for the development and design of suitable and viable water treatment alternatives. A crucial aspect of this is proper evaluation of mine site water balances and implementation of appropriate water management systems. There are many water treatment alternatives that can be used at mining operations, none of which are applicable in all situations.

Pre-Course e-Learning

Prior to the course, registered delegates have access to the online e-learning material consisting of two introductory courses titled A Global Perspective on Cyanide Use and Management and Cyanide Management in Mining - 1.

Certificate in Mining Studies

This course qualifies for two days of short course credit for the Certificate in Mining Studies (CMS), a continuing education program of accredited short courses, webcasts and online courses for lifelong learning in mining, supported by University of British Columbia, University of Arizona and University of Concepción. more details »

Please confirm with your employer and/or professional association that this course qualifies for CPD.

Who Should Attend?

The course will be of particular interest to academics, consultants, agency and regulatory personnel, corporate and operational process and environmental staff, as well as auditors for the new Cyanide Code.

Dr. Terry Mudder

For twenty years until 2014, Dr. Terry I. Mudder was co-owner (with his wife, Dr. Karen Hagelstein) of Times Limited, a consulting firm located in Sheridan, Wyoming (USA). He was previously employed as Chief Environmental Engineer and Research Chemist at the Homestake Mine, and later a partner and corporate consultant with SRK Consulting. Dr. Mudder holds B.S. and M.S. degrees in Chemistry, and a Ph.D. in Environmental Science and Engineering. He has more than three decades of experience in investigation of various aspects of cyanide wastes. He served as an adjunct professor, guest lecturer, and thesis advisor at universities worldwide. He has worked on scores of mining projects, authored nearly one hundred publications, and been involved with numerous short courses, many with Edumine, on acid mine drainage, rehabilitation, and cyanide. As a leading expert on cyanide in mining in the world, he has co-authored many manuals, pamphlets, and books, including the CDs entitled The Chemistry and Treatment of Cyanidation Wastewaters, The Cyanide Monograph, and The Cyanide Compendium.

Dr. Mudder has been instrumental in developing and applying novel chemical, physical, and biological treatment processes for which he has received international awards and patents. He has been a member of many national and international scientific organizations and associated professional committees, as well as a manuscript reviewer. He has been the Technical Advisor for Mining Environmental Management for nearly a decade, for which he has written numerous editorial and opinion articles. He co-created the cyanide information website, CyanideMine. In February 2014 Dr. Mudder was inducted into the International Mining magazine's Hall of Fame and was recognized with an award in Environmental Management and Stewardship.

Dr. Mudder co-sponsored the Dr. Adrian Smith Award given to outstanding individuals for lifetime achievement in environmental stewardship in mining. He has served as technical advisor to aboriginal groups, various industries, international governments, and NGO's including the World Bank, the International Finance Corporation, and the United Nations Environmental Program (UNEP).
