Gold Mining And Assaying Classic Reprint PDF Download

Excerpt from The Metallurgy of Gold: A Practical Treatise on the Metallurgical Treatment of Gold-Bearing Ores, Including the Processes of Concentration, Chlorination, and Extraction by Cyanide, and the Assaying, Melting, and Refining of Gold In this volume my aim has been to present in a condensed form such an account of the several processes which are generally used for the Extraction of Gold from the Ore as shall be sufficient for the full information of investors, and others interested in gold mining operations, who may wish to gain an intelligent insight into the modus operandi at the gold mines. At the same time I have given full descriptions, with illustrations, of the machinery employed in those processes, in sufficient detail to make the book of substantial value to professional men and manufacturers concerned in the gold-mining industry. The treatment of gold-bearing ores, although at one time so uncertain in its results as to be, not only a hazardous, but almost a purely speculative business, has now, through continued improvements in appliances and the adoption of more economical methods, developed into a settled industry, in which more or less profitable results may be obtained even from comparatively low grade ores.
