Excerpt from The Metallurgy of Silver: A Practical Treatise on the Amalgamation, Roasting, and Lixiviation of Silver Ores Including the Assaying, Melting, and Refining of Silver BullionThe object of this volume is to give a practical outline of the Metallurgical Treatment of such Silver Ores as are adapted to Amalgamation-that is, of ores whose character allows them to undergo treatment with quicksilver, with which metal silver forms an amalgam.The processes of amalgamation may be classified as the Wet Process and the Dry Process. Ores which require no preliminary chemical preparation are adapted for direct amalgamation by the wet process. Ores which have to be treated by the dry process have to be crushed dry, and are roasted before being submitted to amalgamation-treatment which involves some very delicate manipulation and skill.Professor Clarence King (in one of his Reports to the United States Government, to which, as will be mentioned presently, I have to acknowledge my indebtedness) has given an excellent account of amalgamation by the wet process; and from this report I extract a description of the Washoe process, as practised on the Comstock lode.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
