Course Summary


This introductory course for professionals looks at four aspects of the cyanidation process: chemistry, analysis, toxicity, and treatment of cyanidation 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.

The chemistry of the cyanidation process is well defined, but its impact on the characteristics of mine waters and the costs of water treatment was often underestimated. In 2000, a global reaction followed the release of cyanide from a tailings dam in Romania. 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.

Today, 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.

This short course aims to:

  • augment the technical skills of process and environmental professionals regarding all facets of cyanide in its relationship to the environment, humans, and mining;
  • provide a knowledge base of sufficient depth to aid those at operations and/or corporate level to develop sound cyanide management plans and help prepare those contemplating participation in the International Cyanide Management Code for Gold Mining Operations;
  • aid those involved in the permitting, design, and operation facets of mining to ask the appropriate questions and make justifiable and practical decisions when it comes to cyanide management; and
  • provide a background of technical information for those manufacturing, transporting, using, regulating, and researching cyanide not only in the mining industry but also industries such as electroplating.

Throughout the course, Dr. Mudder incorporates his extensive, first-hand experience from investigations of various aspects of cyanide wastes to support and enrich the learning for participants.

Who Should Attend?

This course is for anyone wanting to increase their understanding of the cyanidation process, including corporate and operational mineral process and environmental professionals, community relations professionals, agency and regulatory personnel, auditors for the Cyanide Code, consultants, and academics.

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 »

Continuing Professional Development (CPD)

Registered participants who attend the entire short course and complete an evaluation at the end of the course will receive a Certificate of Attendance, confirming the Professional Development Hours (PDH)/Continuing Education Units (CEU) earned. Please confirm with your employer and/or professional association that this course qualifies for CPD.

Dr. Terry Mudder

Dr. Mudder has over three decades of experience in the investigation of the analysis, chemistry, fate, monitoring, toxicity, and treatment of cyanide- and metals-containing wastes and is considered the leading international expert on environmental issues related to cyanide in mining.

In 2000, he was one of the original participants invited to Paris to formally discuss the creation of an international code for the management of cyanide in the gold mining industry sponsored by the United Nations Environmental Program. Later he served as the technical advisor to the International Cyanide Management Institute (ICMI).

Dr. Mudder has been instrumental in developing and applying innovative chemical, physical, and biological treatment processes, for which he has received patents as well as national and international awards, including the prestigious Philip Morgan Medal of the Water Environment Federation. In 2013, he was inducted into the International Mining Technology Hall of Fame for his biotechnology and environmental engineering contributions to the mining industry over the past three decades.

For twenty years, he co-owned TIMES Limited with his wife Dr. Karen Hagelstein, an environmental science and engineering consulting firm based out of Wyoming, USA. Since 2014 he has been consulting on a sole proprietor basis. He was formally a partner, office manager, and corporate consultant for SRK Consulting, an international mining consulting firm. Prior to consulting, he served as Chief Environmental Engineer and Chief Research Chemist at the Homestake Mine in South Dakota, USA, where he along with James Whitlock developed the first full-scale process for the microbial degradation of cyanide in mining wastewater.

Dr. Mudder has served as adjunct professor, thesis advisor, and quest lecturer at several colleges and universities in Australia, Canada, and the United States. He has received the prestigious Guy March Medal from his Alma Mata, the South Dakota School of Mines and Technology, as an outstanding alumnus. He has also served as technical advisor to aboriginal groups, various industries, international governments, and NGOs including the World Bank, the International Finance Corporation, and the United Nations Environmental Program (UNEP).

He has worked on scores of mining projects, authored nearly one hundred publications, and been involved with numerous short courses 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 holds B.S. and M.S. degrees in Chemistry, and a Ph.D. in Environmental Science and Engineering.
