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.

Book Synopsis The Dredging of Gold Placers (Classic Reprint) by : John Ernest Hodgson
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.

Book excerpt: Excerpt from Gold Dredging Enumeration of these latter, howe\ er, may serve to mark the failures of inventors in the past, and thus warn their successors against similar attempts. Undei the heading of obsolete machines may be classed the pneumatic caisson, the submarine boat, the hydraulic. Elevator, and the vacuum dredge. The pneumatic caisson was on the principle employed in making cylinders for the piers of bridges. In it, the diver was let down so as to work direct on the bed of the river. This might be all right for a rich patch, the situation Of which was exactly known; but, for men-day work, where much barren stuff had to be lifted, it proved a lamentable failure. Submarine boat, on the principle of the diiing bell, is said to ha\e been con structed, but never used. Dredging operations using the principle of the hydraulic elevator were attempted on the Chestatee River, Lumpkin co., (ia., but proved unsuccessful, the elevator being out of place in a river bed, many feet below the lewl Of the water, Since most of its work consisted in raising water that did not contain gold. The Bazin dredge was one of the first worked on the vacuum system. The principle upon which the vacuum in this machine was obtained lay in the difference of level between the water outside and the bottom of the bull, in consequence of which the water was forced up the suction-pipe projecting down from the hull to the river bed, and in doing SO carried up the auriferous sands. A centrifugal pump re ceived all the matter forced into the tube, and, adding fresh impulse to its progress, delivered it to the washing appliances. A disad vantage Of this form of dredge was that it required a considerable depth of water in order to produce the requisite amount of vacuum for efficient work. This defect led to the introduction of steam vacuum dredges. The boat was fitted with a boiler and steam pump, 0, each connected with a vacuum chamber, from which projected the.

Book excerpt: Excerpt from Placer Mining for Gold in California The increase in the price of gold from in 1932 to in 1933 and to in 1934 made such stories seem even more plausible and helped further to stimulate the migration of men to the creeks, despite the unfortunate experiences related by most of those drifting back from the gold-bearing areas. Stories of those who succeeded in making a living and of the very few who made strikes continued to be magnified out of all proportion, both in passing from mouth to mouth and in the press, and brought new recruits to the streams as late as 1937.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Famous Gold Nuggets of the World In these days of wonderful gold discoveries one is apt to forget the big finds of the past, which set the world wild with excitement and gave such impetus to mining about half a century ago. This brief account of famous gold nuggets will help to revive the memories of the golden days of Australia and California, and to show how history tends to repeat itself in gold mining as well as in other mundane affairs. The data has been gathered from many sources, involving a large amount of research, which extended over the face of the globe. In procuring this information the compiler has corresponded with some two hundred persons, to many of whom he is indebted for whatever credit may be attached to his efforts. He ventures to believe that the result will be found of deep interest to all concerned in mining and mining matters. For much of the material used the compiler is indebted to the Engineering and Mining Journal and American Mining News, of New York; the Mining and Scientific Press, of San Francisco; Mining Reporter, of Denver; Mining Record, of Colorado Springs; the Australian Mining Standard, of Melbourne; Mining and Metallurgical Journal, Los Angeles, California; ex-United States Mining Commissioner R. W. Raymond, and representative mining engineers residing in all parts of the world. With one exception, no mention is made of nuggets found in South America or Mexico, the compiler having been unable to collect reliable data from these countries, excepting as to their gross gold and silver output.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Sixteen Months at the Gold Diggings It is almost inconceivable what an excitement was produced upon nations and individuals by the discovery, less than four years since, of gold among the mountains of Upper California. Tides of human life soon set in toward this one point; currents here met, whirling and contending with increasing force; and, where all was silent and calm before, was heard the roar, and seen the violence and agitation of the maelstrom. The writer was for sixteen months employed in the gold mines, chiefly upon the American and Tuolumne Rivers and their tributaries. His reasons for compiling his notes and presenting them to the public may be briefly stated. It was the request of several friends that he would keep a journal of his mining life, exhibiting its lights and shades, its fortunes and misfortunes. This he did, jotting down from day to day the incidents as they occurred. Many mining companions, aware of this fact, requested him to prepare his journal for the press, that their friends might thus have a view of their circumstances and employments.
