Book Description
Excerpt from The Mining and Metallurgy of Gold and Silver His object has rather been to render this volume practically useful as a record of well-authenticated facts, and of the results of actual experience, than to advance new theories, or to accumulate additional evidence in support of old ones. He has, therefore, contented himself with merely stating the results both of his own observations, and those of others; or at most with suggesting the nature of the forces producing the effects described. He believes that our knowledge of chemical geology is not, as yet, sufficiently advanced to warrant an attempt to form a general theory of the formation of mineral veins. Recent observations and experience appear, however, to lead to three important conclusions. First, that the most productive gold bearing rocks are by no means exclusively confined to the Silurian period; secondly, that aqueous agencies have been, and still are, actively at work in the formation of mineral deposits; and, thirdly.

Book Description
Excerpt from Roasting of Gold and Silver Ores and the Extraction of Their Respective Metals Without Quicksilver The Solving Process is very simple, and readily performed by common workmen; besides the lime, only brimstone must be provided, in order to prepare the necessary chem icals for solving and precipitation. It is a general but erroneous belief, that the solving is a slow process. An amalgamating pan is charged with 500 to pounds of roasted ore, and treated at least six hours, and therefore turns out at most two tons in 24 hours while a box or vat of proper size used in the Solving Process, can work from four to five tons in the same time.

Book Description
Excerpt from Nevada and California Processes of Silver and Gold Extraction: For General Use, and Especially for the Mining Public of California and Nevada I have prepared the text of this work with care, and supplied the first part with distinct and detailed drawings, so that one by studying it can learn to perform all the Operations. If, however, there are yet many things not satisfactorily explained, or not thoroughly treated, it may be attributed to the circumstance that our metallurgy is very young.

Book Description
Excerpt from The Metallurgy of the Common Metals: Gold, Silver, Iron, Copper, Lead, and Zinc This outline of the metallurgy of the common metals, namely, gold, silver, iron, copper, lead, and zinc, is devoted to the description of processes for winning these metals from their ores and then refining them. The metallurgy of iron is treated only to the point where pig-iron is obtained. Following the description of ores, as well as of the fuels used in smelting them, and the materials of which the furnaces are con structed, we come to sampling, for the determination of the exact value of the ore before treatment. A chapter has been devoted to the subject of thermo-chemistry as applied to igneous methods of extraction. The winning or reduction of' the various metals is then taken up in order, and is followed by. A description of the methods of refining them. Attention is then given to commercial considerations, since the processes must be conducted in a profitable way.
