Book excerpt: Excerpt from The Cyanide Process of Gold Extraction: A Text-Book for the Use of Metallurgists and Students at Schools of Mines, Etc In the hands of different metallurgists and chemists the cyanide process has made rapid strides during the past few years, more especially in the designing of plants and mechanical appliances to reduce the cost of treatment. At the Witwatersrand Goldfields it is used on a very large scale for the treatment of tailings, the operations being conducted with much skill and economy under the supervision of noted metallurgical chemists and engineers.

CHAPTER TIL LABORATORY EXPERIMENTS. The cyanide process is essentially a chemical one, and a commodious and well-equipped laboratory forms one of the most important and necessary parts of the whole plant. It is the duty of the metallurgist in charge to determine by actual experiment the lowest strength of cyanide solution to extract an adequate percentage of the gold, and also to devise means of overcoming the problems which are inseparable from the treatment of different classes and grades of ore, with so active and subtle a compound as potassium cyanide. The testing and valuing of the ores before, during, and after treatment must be entrusted to a careful and trustworthy assayer. The testing and making up of the working solutions are very simple operations, that may be left to experienced and intelligent workmen who possess a knowledge of arithmetic extending as far as decimals. With free-milling gold ores the actual working extraction will generally be as high as that obtained in the laboratory, but too much reliance must not be placed on the laboratory experiments in the case of ores containing copper or antimony. The author, s experience is that high extractions may be obtained in the laboratory from ores totally unsuited for treatment by the cyanide process on a working scale. The conditions on the one hand are theoretical, on the other actual, and before adopting the cyanide treatment for a sulphide or mineralized ore, working experiments should be made on parcels ranging from two to five tons, in order to ascei-tain the consumption of cyanide and actual extraction. If the working trials are successful the cyanide treatment may be adopted with confidence. On the other hand, in the case of an ore containing comparatively coarse..

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Cyanide Process of Gold Extraction: A Textbook for the Use of Mining Students, Metallurgists, and Cyanide Operators The exhaustion of the last edition has enabled the author to revise the text and add much new matter relating to recent improvements in cyanide practice in different parts of the globe. The principles underlying the treatment Of silicious silver ore carrying more or less gold is dealt with more fully than in former editions. The weak point in the present treatment of these ores is the low extraction of the silver. At the current price of silver this is perhaps not of much moment with ores in which the chief value lies in the gold contents but in the case of low-grade silver ores carrying from 1 to 3 dwt. Of gold, and from 10 to 20 oz. Of silver, per ton, the subject is one of increasing concern to the mine owner. The difference between an extraction of 50 per cent. And 85 per cent. Of the silver may represent the sole margin of profit in a low-grade venture. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
