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.
The history of metallurgy in Canada since 1900 represents a vast historical topic. This report seeks to provide a coherent summary by focussing on three core themes: the histories of major companies involved in the production of base metals, the nature and evolution of metallurgical engineering, and significant Canadian contributions to the international field of metallurgy. Each theme is discussed in a chapter of this report. This broad overview makes it possible to address fundamental questions, particularly whether Canada experienced a “golden age” of metallurgical research and development that spanned the second half of the twentieth century, and, if so, whether this period has come to an end.
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.
While a great deal of literature on project and construction management exists, as do many reference books on the fundamentals of metallurgy and engineering principles, very little information is available on the design process, which translates these fundamentals into the design of a properly functioning metallurgical facility. This book fills the information gap.
“Women of Impact” is a celebration of women’s achievements in science and engineering. Based on in-person interviews, this collection profiles eighteen women who have made significant contributions to the fields of materials, metallurgy, and mining in Canada. Their compelling stories and impressive achievements reveal how women have defied stereotypes, pushed through barriers, and passionately engaged with their industry
