Paperback. Condizione: New. Print on Demand. This book explores the development of gold mining and milling systems over a 15-year period. The author argues that many of the methods considered groundbreaking and effective are actually nothing new. Instead, they are old and familiar techniques, sometimes simply repackaged for new…audiences. Drawing on data from companies and official reports, this book establishes that the average loss of gold during the milling process is low, making the expensive and complex systems implemented by mining companies a waste of resources. The book offers an in-depth look at gold amalgamation systems and the failures companies have encountered when adopting new machinery. The author then proposes a compromise solution of employing greater skill in copper-plate amalgamation, finer crushing, concentration, and more effective treatment systems, which can significantly reduce the loss of gold and produce higher returns. 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.
