A Treatise On Metalliferous Minerals And Mining

Excerpt from A Treatise on Metalliferous: Minerals and Mining IN revising this book for the Fifth edition, I have endeavoured, while making additions wherever they seemed to be necessary, to keep within the original design of the work as laid down by my father in the Preface to the First edition. The advances made in the knowledge of particular minerals, and of their distribution throughout the globe, as well as in the adaptation of processes and machinery for the treatment of ores, since the book was first written, have necessitated the insertion of much additional matter, increasing the volume by nearly 100 pages. Thus, recent experiences of the Treatment of Refractory Gold Ores, and the later development of the processes of Concentration and Chlorination, have been fully noticed; while (besides the enlargement of existing chapters) two new chapters - on the Treatment of Zinciferous Ores and the Sale and Sampling of Lead Ores - have been added. About twenty new illustrations are also given. I trust that these new features will be found to enhance substantially the value and utility of the work.

Excerpt from Machinery for Metalliferous Mines: A Practical Treatise for Mining Engineers, Metallurgists and Managers of Mines The continued favour awarded to the mining works of my father, the late Mr. D. C. Davies, F.G.S., coupled with the recent advances and improvements in mining machinery, has created a demand for a more comprehensive and detailed description of the Machinery used in Metalliferous Mines than was permissible in the few chapters devoted to that subject in my father's work on Metalliferous Mines and Mining, the Fifth Edition of which, revised and enlarged by myself, has recently been published. The present work, therefore, is designed as a companion volume to the former, and is devoted exclusively to the description of the various machines in daily successful use in mining, both for the extraction and transport of the ore, and for its concentration and preparation for the market. It does not deal with the occurrence of mineral lodes, nor does it attempt to exhaust the list of the numberless new processes and new patents which the fertile brains of inventors are almost daily bringing before the public, only too often to attract a brief attention and never to come into practical use.
