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.
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.
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.
