Heap Leach Solutions 2016 was the fourth in this conference series created in 2013 in Vancouver by InfoMine and the University of British Columbia (UBC). The series has quickly become a highly acclaimed forum in the field of heap leaching, as demonstrated by the very successful conferences held in 2013 in Vancouver, Canada, in 2014 in Lima, Peru and in 2015 in Reno, Nevada, USA. With this conference series we seek to share knowledge and facilitate interaction between heap leach practitioners and researchers from a wide range of disciplines. Theory and practice are very well balanced in the conference programs, which discuss various aspects of the activities during the life cycle of a heap leach project, from ore testing to development and operations, and, finally, closure.


This conference was relevant to everyone engaged in the development, design, construction, and closure of heap leach projects, including academics, regulators, and personnel from mining, consulting, engineering, and financial companies. The range of technical topics included hydrometallurgy, process engineering, geotechnical and hydrogeological engineering.

Proceedings of the First International Conference on Heap Leach Solutions

September 22-25, 2013 | Vancouver, Canada

  • Product: Digital book (e-book) of proceedings, for downloading to PC or Mac
  • Language: English

Many technological, regulatory and economic developments have resulted in much more sophisticated planning for the development, operation and closure of heap leach facilities. While heap leaching remains an appropriate recovery method of metals at lower capital and operating costs in drier climates, modern heap leach operations are currently being developed and run in a much broader range of climatic conditions. Many professionals have worked extremely hard for more than 30 years to establish much more robust projects.

The published papers and presentations represent a very good snapshot of the range of aspects that must be considered for successful heap leach projects. This volume reflects a synthesis of global knowledge, research and practical experience of heap leaching. As such, it will become a very useful reference document for the development of future projects, and in the education and training of young professionals involved in heap leach practice all over the world.

This publication comprises a total of 46 papers.

Technology reviews

TechnoMine, a division of InfoMine, is a leading source of online information about technology for the mining and geoscience communities. It provides insightful articles, news, reviews, and resources on mining technology and related topics. We invite you to browse the following technology reviews related to heap leaching.

Heap Leach Pads

This review looks at the basic concepts of heap leaching and describes the various types of heap leach pads. It also explains the design considerations for heap leach pads. Performance and stability of the pads are also discussed, and links to several software are given.

Design for Closure

This review describes the design of mines and mine facilities, including infrastructures, open pits, underground mines, tailings facilities, waste rock dumps, heap leach pads and other waste disposal facilities for closure. It lists technology resources, websites, case histories, and consultants that discuss the design of mines for closures. It also includes consideration of the current and future costs of mine reclamation, restoration, and long-term surveillance and maintenance post-closure.
