Paperback. Zustand: New. Print on Demand. This book guides directors and millmen alike on gold processing insights developed before 1890, focusing on the practical, commercial handling of various ores. The author emphasizes the importance of understanding the condition in which gold is lost within a particular oreâ"free, locked…in particles, or mixed with sulphuretsâ"and provides simple tests for determining this. The author encourages a focus on maximizing the percentage of gold saved, rather than on overall yield, and notes the crucial role of concentration techniquesâ"particularly the Frue vannerâ"in minimizing losses. A useful distinction is drawn between ores amenable to copper-plate amalgamation and those better suited to chlorination or smelting. While acknowledging the potential of new inventions, the author cautions against hasty adoption and advocates a conservative approach, emphasizing the value of proven processes and experienced personnel. The book's insights on minimizing gold losses and selecting appropriate treatment methods remain relevant today, offering valuable guidance for those involved in the mining and processing of gold ores. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
