Download or read book The Dredging of Gold Placers Classic Reprint written by John Ernest Hodgson and published by . This book was released on 2015-07-21 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Dredging of Gold Placers During the past two years the writer has contributed to English and American periodicals several articles, dealing with the phase of mining to which the following pages are devoted. Some interest appears to have been aroused among both mining men and the lay public by these articles, and the wish has often been expressed that they should be incorporated in one volume. This book is an attempt to meet that desire. The industry is a comparatively new one, and the views of dredging men in regard to many questions, both of construction and design, are still in a state of flux. This book is offered to the world, therefore, not by any means as a technical work, but in the sincere hope that it will help and interest company directors, property managers, prospectors, and those of the investing public who have acquired, or think of acquiring, a share interest in a gold-dredging concern.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Gold Dredging in the United States The recovery of gold from sands and gravels is one of the oldest forms of mining; it antedates history and has been practiced by savage peoples. In North America the search for placer gold has been a powerful agency in the exploration and development of unknown regions and has profoundly influenced the course of our civilization. With the progress of invention, the improvements in machinery, and the availability of large capital for the conduct of great operations, the tendency in placer, as in many other branches of mining, has been toward the working of extensive but comparatively low-grade deposits. The early miner washed the rich spots in stream beds or terraces with his pan, his long tom, and his primitive sluice. Then followed the growth of hydraulic mining and the use of giants supplied with water under pressures of hundreds of pounds to the square inch that could work at a profit gravels whose gold tenor was less than 3 cents to the cubic yard. Finally came the dredge that could handle deposits lying so far below water level as to be beyond attack by other methods. Although the gold dredge was first successful on a commercial scale in New Zealand, it has reached its present strength and efficiency in this country and its development is a monument to the daring, per severance and technical skill of the many men, mine owners and engineers who have each contributed something to the final result. The Bureau of Mines, authorized to conduct investigations for the purpose of increasing efficiency in the mineral industries, had its attention called some years ago to the need of a comprehensive report on gold dredging in the United States. The director of the bureau recognized that such a report should summarize the development of the gold dredge, should describe in detail the essential features of present-day dredges, should discuss the facts that determine whether a placer deposit can be profitably dredged, and should point out the approved methods of prospecting placer ground and of operating dredges.
