This is a report about the cyanide process and its application for extracting gold and silver from their ores. The cyanide process works by dissolving the gold or silver into a solution. Authored by Dr. A. Scheidel. Issued by the California State Mining Bureau. J. J. Crawford is credited as State Mineralogist. The following are the titles of the sections: "History of the process," "Scope of process," "Chemistry of process," "Percentage of extraction," "Working costs of production," "Cost of cyanide plants," "Machinery and appliances," "Laboratory work," "Danger in working the process," "Exemplification of the process," "Summary and conclusions," and "Patents" (in Appendix). The following excerpt from Page 5 explains the cyanide process in more detail: "The "cyanide process' for extracting gold and silver from ores is based on the fact that a diluted solution of potassium cyanide dissolves these metals, forming, respectively, auro-potassic cyanide and argento-potassic cyanide, from many ores, without dissolving to any material extent the other components thereof. The process consists of treating suitable ores, when finely divided, with a weak solution of potassium cyanide, either by allowing the solution to percolate through the ore or by agitating a mixture of the ore and solution. This part of the operation being completed, the solution is separated from the solid material and the gold and silver are precipitated in metallic form. This process for the extraction of gold and silver is comparatively old in its principle, but modern in its technical application. During the last four years it has been introduced into almost every gold field, and upward of $14,000,000 in gold and silver have been recovered by the process, which demonstrates beyond a doubt that it is one of the most important additions to the wet methods of gold and silver metallurgy.".

Paperback. Condizione: New. Print on Demand. This book showcases the history and practical applications of the cyanide process for extracting gold and silver from ores, detailing the process's development from its roots in laboratory experiments to its implementation in gold fields and mines worldwide.
