Sustainable Materials Recovery Processes

This book reviews the principles and challenges of biomining, bioflotation, and membrane separation technologies as applied to the hydrometallurgical field, including recent technological developments. It explores the evolution of biomining and bioflotation within the hydrometallurgical industry over recent years, emphasizing the increasing diversity of bioreagents, their mechanisms of action, and the classification of processes based on their fields of application. The book also discusses the sustainability of mineral processing technologies.

• Provides valuable insights into innovative technologies and methodologies that enhance sustainability in mineral recovery processes
• Brings together biological and membrane-based technologies within a single comprehensive volume
• Discusses the impact of bioengineering on the advancement of biomining and bioflotation
• Explores interactions between microorganisms and minerals
• Reviews the use of biomining for the beneficiation of precious metals from secondary minerals

This book is intended for graduate students, researchers, and professionals in mineral processing, hydrometallurgy, geochemistry, environmental science, and chemical engineering.
