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. Find more at ...
