Marsden Chemistry of Gold Extraction

This book provides an in-depth examination of the principles and practices involved in the extraction of gold from ores. The primary objective is to furnish readers with a comprehensive understanding of the chemical processes underpinning gold extraction methods, along with the technological advancements that have shaped this field. Methodologically, the text combines theoretical insights with practical applications, addressing various hydrometallurgical techniques, including the use of cyanide and alternative lixiviants, ion exchange resins, and solvent extraction methods. Each chapter presents empirical data and case studies that illustrate the effectiveness and challenges of these techniques. Results indicate that while traditional methods such as cyanide leaching remain prevalent, there is an increasing interest in developing more environmentally sustainable approaches to gold extraction. The book also emphasizes the importance of recovery processes and surface chemistry in maximizing gold yield. Ultimately, this second edition serves as both an educational resource and a reference for professionals in the mining and metallurgical industries seeking to enhance their knowledge of gold extraction strategies.
