Course Summary


This course is for those who want to gain a basic understanding of/get an introduction to design, construction, operational, and closure considerations for a heap leach facilities. The course draws on and expands on a series of Edumine courses, including those that deal with heap leach pad design and operation, the geotechnical performance of mine waste facilities, and mine closure.

The webcast will be held separately from, but in close cooperation and conjunction, with the InfoMine conference, Heap Leach Solutions 2014.

The presenters include those who have written the Edumine courses on heap leach pads, consultants who specialize in heap leach pad design and construction, and academics who have devoted their careers to the research issues of heap leach pads.

The InfoMine Conference Associated with the Webcast

Heap Leach 2014 is a comprehensive conference that will bring a range of professionals together to present new research insights and share leading practices on heap leach projects. This conference will address the planning, design, operation, closure, and research aspects of heap leaching. Conference sessions will include presentations related to gold/silver, copper, and nickel heap leaching. For further short courses held during the conference, please see the conference short courses page.

Pre-Course e-Learning

Prior to the course, registered delegates have access to the online e-learning material consisting of two introductory courses titled Heap Leach Pads and Heap Leach Design.

Certificate in Mining Studies

This course qualifies for one day 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 ConcepciĆ³n. more details »

Continuing Professional Development (CPD)

Registered participants who attend the entire webcast 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.

Who Should Attend?

This course is for everyone associated with heap leach facility design, construction, operation and closure, including mining engineers, civil engineers, mechanical engineers, metallurgists, environmental specialists, hydrologists and hydrogeologists who would like to understand factors that are involved with heap leach pad design, operation and closure.

Jack Caldwell

Jack Caldwell, P.Eng, has a B.Sc. in Civil Engineering, an M.Sc. (Eng.) in Geotechnical Engineering and a post-graduate law degree. He has over 35 years engineering experience on mining, civil, geotechnical and site remediation projects. He has worked on numerous projects throughout southern Africa, Europe, Latin America, Canada, and the United States. His project experience includes:

- mines and waste disposal facilities - design, construction supervision and reclamation of tailings impoundments, mine rock dumps, heap leach pads, landfills and radioactive waste disposal units;

- hazardous and radioactive waste site remediation - senior management and technical consultant

- landfills - design, construction, operation and closure with special focus on liners, covers, and soil reinforcement.

In addition, Mr. Caldwell has been the lead specialist for various geotechnical and civil engineering projects in Southern California. Mr. Caldwell has written many engineering reports, proposals, and technical papers. He is the lead author of the book, Principles and Practice of Waste Encapsulation, on the design of waste disposal facilities for radioactive and hazardous wastes.

Dirk van Zyl

Dirk Van Zyl is Professor and Chair of Mining and the Environment at the Norman B. Keevil Institute of Mining Engineering, University of British Columbia, Vancouver, BC. Dirk has more than 35 years experience in research, teaching and consulting in tailings and mine waste rock disposal and heap leach design. During the last decade much of his attention has been focused on mining and sustainable development and mine life cycle management.

Dirk has consulted internationally on many mining projects. These projects covered the whole mining life cycle, from exploration to closure and post-closure, in a large range of climatic and geographic environments. Most of this work has been focused on geotechnical and environmental mining engineering aspects to provide solutions for environmental and human health protection.

Dirk has more than 100 publications to his credit; these include papers and book chapters. He has also presented numerous short courses on heap leach design, mining environmental management and mine closure in the US and abroad. He is the recipient of the three awards from the Society for Mining, Metallurgy and Exploration (SME). These are the Robert Peele Award (1985) and Distinguished Service Award (1992) from the Mining and Exploration Division, and a President's Citation (1998). Dirk became a Distinguished Member of SME in 2003. He received the Bureau of Land Management Sustainable Development award in 2005 and the Adrian Smith International Environmental Mining Award in 2006.

Dirk received a B.Sc. in Civil Engineering in 1972 and a B.Sc. (Honors) Civil Engineering in 1974, both from the University of Pretoria, South Africa. He also received M.S. and Ph.D. degrees in Geotechnical Engineering from Purdue University in 1976 and 1979, respectively. In 1998 he completed an Executive MBA at the University of Colorado. He is a registered professional engineer in 3 States in the US.

His experience includes the design and construction of heap leach and tailings facilities. His responsibilities typically include site selection, risk assessment, site investigation, laboratory analysis, slope stability assessment, data interpretation, costing analysis, and development of specifications, construction drawings, bid documents and construction programs. His project experience has included conceptual through final design engineering, preparation of construction documents, subcontractor selection, and construction management and supervision. He has also managed multi-disciplinary engineering teams on international mining projects.

Ian Hutchison

Ian Hutchison is a fifty-year veteran of mining. He has consulted to the largest international mining companies on tailings, waste rock, and heap leach facilities. Ian specializes in mine waste management planning, surface and groundwater aspects of mining, and the chemistry of wastes and their impact on the environment. In his consulting practices, he manages a staff of over thirty and understands the need of the most junior through to the most senior engineers and scientists working on small and large mine waste disposal facilities. He wrote the book on Mine Waste Management for the California Mining Association in California, USA.
