Course Summary

Introduction

This course is designed for anyone concerned with the use and treatment of cyanide in mining. It provides a detailed accounting of the usage of cyanide for extraction and recovery of gold, and of cyanide toxicity and chemistry, and the available treatments for cyanide detoxification and cyanide recovery. The topics covered include...

  • cyanide usage
  • gold cyanidation
  • cyanicides and oxygen consumers
  • gold recovery methods
  • cyanide toxicity
  • cyanide treatment
  • cyanide recovery

Course Content

Cyanide in Mining comprises eight viewing sessions at both summary and text level of 30 to 60 minutes duration each, plus multiple-choice reviews, and supporting figures, design tables and references. Course duration is equivalent to approximately 8 hours of viewing content.

Learning Outcomes

  • Discuss the usage of cyanide for extraction and recovery of gold.
  • Discuss the toxicity and chemistry of cyanide.
  • Discuss the available treatments for cyanide detoxification and cyanide recovery.

Recommended Background

  • A partial degree or diploma in geology, mineral processing, mining engineering or related discipline.

Marcello Veiga

Dr. Marcello Veiga has worked for the past twenty five years as a metallurgical engineer and environmental geochemist for mining and consulting companies in Brazil, Canada, US, Venezuela, Chile and Peru. He has worked extensively on environmental and social issues related to mining. As a professor of the Department of Mining Engineering at the University of British Columbia, since 1997, his research topics include: sustainable development in mining, mine closure and reclamation, remedial procedures for metal pollution (in particular mercury pollution, bioaccumulation and adverse effects of metals in the environment), acid rock drainage, and mineral processing. For 2 years, he worked as an expert for UNIDO - United Nations Industrial Development Organization, in Vienna, on issues related to artisanal gold mining in Asia, Africa and South America. Since Aug 2004, he is back to UBC to his academic activities.

Bern Klein

Dr. Bern Klein is a Professor of Mining Engineering at the Norman B. Keevil Institute of Mining Engineering at University of British Columbia (UBC). Bern's research interest has long been the production of minerals and chemical processing technologies. After completing both his B.A.Sc. and Ph.D. in Mining Engineering at the University of British Columbia, Bern spent eight years as a consulting process metallurgist before Rick Lawrence, the Department Head of what was then UBC Mining and Mineral Processing Engineering, invited him to apply for an opening on the faculty. Bern accepted the invitation, hoping both to expand the type of work that he had been doing in consulting, and to contribute to the future of the Department and the industry.

He has certainly succeeded in those endeavours. Not only has he been published extensively in his areas of research interest (including industrial minerals, ultrafine grinding, high pressure grinding rolls, hydraulic transport of non-Newtonian mineral slurries, metal leaching from waste rock, rheology of mineral suspensions, and improved technologies for artisanal and small scale gold miners), he also serves as the Director of UBC's Center for Industrial Minerals Innovation (CIMI), Faculty Supervisor in the Center for Coal and Mineral Processing (CMP) Laboratory Facility, and as UBC Mining Industrial Liaison.
