The inspiration for this book came from Professor Ed Asselin and the desire to disseminate expert knowledge and insights from experienced professionals in the field of copper hydrometallurgy. Examples of recognizing and effectively meeting challenges and applying established and front-line knowledge and practical insights are provided in this book. The hope is that practitioners in the field will find the material in this book to be practically useful. If the reader could sit down with the authors of this book and "talk shop", this is the kind of material that would likely inform those conversations.
The book begins with an overview of the thermodynamics of leaching. Choosing thermodynamic data wisely is considered and then how to make use of those data to gain a sense of what is possible. Arguably, the key step in hydrometallurgy is leaching. The next four chapters deal with leaching in detail, including kinetics, heap leaching, concentrate leaching, and bioleaching. Solvent extraction for the most part follows leaching in practice and is developed next with a focus on practical considerations. Metal production by electrowinning and purification by electrorefining follow in the next chapter, which focuses on practical aspects and reviews state-of-the-art developments. Finally, applications of ion exchange are considered as versatile means to solve several purification problems in copper hydrometallurgy.

A handful of Canadians, awakened by the potential of new technology, made Canada the foremost nation in the world in the exploration of mineral resources. Author Norman Reed Paterson, respected worldwide for his innovations in geophysical technology and his indomitable spirit of exploration, takes the reader into the bush, the laboratory, and the office—often with humour—to observe the key players who, through determination and willingness to take risks, showed the world a new way to find mines.
CIM’s Special Volume 57 is the third volume in a series of books dedicated to porphyry deposits of the northwestern Cordillera and is timely, given the increased levels of exploration for precious and base metals seen throughout western British Columbia, southwest Yukon and southern Alaska over the past number of years. With the increasing importance of copper in the sustainable future of global society, this volume presents a series of papers focused on porphyry deposits, the major source of this green metal globally, structured into two sections.
Section 1 comprises informative and detailed reviews of the porphyry-related metallogenic evolution of key belts throughout the Cordillera, possible linkages between porphyry and epithermal deposits in some important districts in British Columbia, greenrock exploration vectors in porphyry deposits, and the potential geological significance of platinum group elements that commonly occur in many porphyry deposits in British Columbia. Section 1 concludes with reviews of recent technological developments in the fields of geometallurgy, and tailings management as relevant to porphyry copper ores. The papers in section 1 provide a solid framework for the descriptions of individual porphyry deposits in Section 2. Some deposits are formally documented for the first time (e.g. IKE, Kwanika and Gnat Pass) and others benefit from updated geological descriptions (e.g., the Kerr-Sulphurets-Mitchell-Iron Cap-Snowfield cluster of deposits, which are all well represented).
This Special Volume will be of interest to geologists, explorers, miners and anyone wanting to learn more about this core part of the mining landscape in Canada and Alaska.

L'histoire de la métallurgie au Canada depuis 1900 représente un vaste sujet historique. Ce rapport cherche à en fournir un résumé cohérent en se concentrant sur trois thèmes principaux : le passé historique des grandes compagnies qui participaient à la production des métaux communs, la nature et l’évolution de l’ingénierie métallurgique et les importantes contributions canadiennes au domaine international de la métallurgie. Chaque thème est abordé dans un chapitre de ce rapport. Grâce à ce large tour d’horizon, il est possible de traiter de questions fondamentales. On cherche particulièrement à savoir si le Canada a vécu un « âge d’or » de la recherche et du développement métallurgique qui se serait étendu sur la deuxième moitié du 20e siècle et, dans l’affirmative, si cette période est terminée.
