Discover the cyanide process in practical, real-world terms .
This State Mining Bureau bulletin explains how dilute potassium cyanide dissolves gold and silver, and how these metals are recovered in metallic form through straightforward steps and proven methods.
This edition describes the process from history to modern application, with emphasis on ores, preparation, and economical results. It ties theory to action with descriptions of agitation and percolation methods, plant layouts, and the equipment used in working operations. The text is illustrated with plans and diagrams to help readers visualize the treatment and recovery steps.
- How cyanide solutions dissolve gold and silver and how metals are precipitated for collection
- Two main methods of operation: agitation and percolation, plus how solutions are processed and recovered
- Economic considerations, costs, and comparisons with other metallurgical methods
- Descriptions of real-world plants, equipment, and countrywide applications
Ideal for readers of mining history, metallurgical practice, and early cyanide-era technology seeking a grounded, historical view of its practical use.
