Book excerpt: Excerpt from Lead, Silver-Lead and Zinc Ores of Cornwall, Devon and Somerset Lead-ores. - On the map it will be seen that each granite mass is surrounded by a belt of highly metamorphosed rocks, and that the lead lodes never occur in the granite and seldom in these belts. The country rock is either a sediment or, more rarely, lava or ash, and never an igneous rock Of intrusive origin. There is a significant association of lead-ore with argillaceous sediments, which is apparently general in Cornwall and Devon; and lodes which course through interfolded beds of Slaty and sandy killas are rich in the former and barren in the latter. This phenomenon is well illustrated by sections (plates III and IV) where the stoped ground is entirely in Shaly killas. The Beer Alston lodes were rich in lead-ore while in Slate, but became barren near the granite. Most of the lodes course from north to south; a few, and those rich ones, course nearly north-east, and one or two in other directions.

Book excerpt: Excerpt from Lead Ores The Imperial Institute is a centre for the exhibition and investigation of minerals with a view to their commercial development, and for the supply of information respecting the sources, composition and value of minerals of all kinds. The Imperial Institute is provided with Research Laboratories for the investigation, analysis and assay of minerals, and undertakes reports on the composition and value of minerals for the information of Governments and producing companies and firms, in communication with the principal users in the United Kingdom and elsewhere in the Empire. Important minerals from within the Empire are exhibited in the respective Courts of the Public Exhibition Galleries, and also in the Mineral Reference Collections of the Institute. A special staff is engaged in the collection, critical revision and arrangement of all important information respecting supplies of minerals especially within the Empire, new methods of usage and other commercial developments. Articles on these and related subjects are periodically published in the Bulletin of the Imperial Institute, and Monographs on special subjects are separately published under the direction of the Committee on Mineral Resources.

With the higher prices prevailing the percentage Of increase in value of the 1915 output was even greater as compared with other years.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lead and Its Compounds IN the present volume the author has endeavoured to.show the great strides made in the metallurgy of lead and zinc, and to incorporate in it the latest applications of electrical science, not only in cleansing the ores, but also in their after treatment. The work also contains a description of the pigments of both metals, their manufacture and properties; and to make this portion as comprehensive as possible, the drying oils and siccatives, and their relation to pigments, are dealt with. In addition to other information of importance to the colourist, the value of the work is enhanced by a chapter devoted to the assaying and analysis of lead and zinc ores, and the quantitative testing of paints and oils. The book is divided into seventeen chapters, and is illustrated with forty drawings, specially made by Mr. Levi Lambert, to whom great credit is due. In conclusion, the author hopes the work will be studied with advantage by those engaged in the above branches of industry.

Book excerpt: Excerpt from The Metallurgy of Lead Silver, Vol. 1 of 2 When silver is melted and cooled slowly, octahedral crystals can be obtained. When melted in the air it absorbs twenty-two times its volume of oxygen, which is, however, given off on solidification. This phenomenon called sprouting is peculiar to silver which is nearly pure, comparatively small quantities of copper or of lead destroying its property of sprouting.

This book was released on 2016-08-18 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Metallurgy of Zinc and Cadmium Although the zinc industry of the world ranks in importance with the copper and lead industries, there has never been printed heretofore a special treatise on the metallurgy of zinc. Such essays on this subject as have been published in generally available form are embodied in the handbooks on general metallurgy and industrial chemistry, which being necessarily brief fail to describe adequately the modern practice in this branch of metallurgy. Besides these there is no literature on the subject save in the files of technical periodicals and the transactions of scientific societies, chie y French and German, inasmuch as the Belgian and German engineers have led the way in this branch of metallurgy, until recently at least.

Download or read book The Metallurgy of Lead written by John Percy and published by Forgotten Books. This book was released on 2017-09-17 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Metallurgy of Lead: Including Desilverization and Cupellation IT was intended that this volume should contain the Metallurgy Of Lead, Silver, and Gold; but it has been found impossible to treat those important subjects in a sufficiently detailed and com prehensive manner in a single volume without making it so thick and heavy as to be inconvenient. It has, therefore, been decided to restrict this volume to the Metallurgy Of Lead, including the processes of Desilverization and Cupellation. The Author does not regret the change in the plan of publication, because the delay in publishing the Metallurgy of Silver and Gold will, there is reason to hope, enable him to procure valuable and additional information from California and elsewhere on those subjects for the next volume, of which a considerable portion is already in print.

This book was released on 2017-09-15 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lead and Zinc Deposits of Northwestern Illinois, Vol. 21 The Galena limestone is by far the most interesting and important mineral-bearing deposit in the State, being the principal depository of the ores of lead and zinc, the former of which has been successfully mined in the vicinity of Galena ever since the first settlement of the country by the French. These mines are Said to have been discovered by M. Le Sener, who made an exploring trip up the Mississippi in the year 1700, but no attempt was made to work the mines until a century later when Julien dubuque, a half-breed of French and Indian descent, obtained a grant of land from the Fox Indians on the west side of the Mississippi, including the present site of the city of Dubuque, and commenced the business of lead mining in 1788, which be prosecuted successfully until his death in 1810. From that time on, the business was gradually extended, and in 1823 the tide of emigration began to flow rapidly from Kentucky and some of the eastern states, toward this Eldorado of the northwest, and in the next succeeding decade, dig gings had extended over nearly the whole extent of the lead bearing rocks of this region, including also that part of the mineral region embraced in the present area of the States of Illinois and Wisconsin.
