Download or read book Fluorspar Mining written by Herbert K. Russell and published by SIU Press. This book was released on 2019-01-03 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first-ever pictorial record of the people and methods of the Illinois-Kentucky Fluorspar District from the 1900s to the 1990s covers early and modern means of extracting, hoisting, processing, and transporting the mineral from mine mouth to end user. Nearly one hundred images carefully selected by author Herbert K. Russell show early pick-and-shovel extraction and open-flame lighting as well as primitive drilling methods and transportation by barrels, buckets, barges, mule teams, and trams, in addition to the use of modern equipment and sophisticated refinement procedures such as froth flotation. Russell also provides an overview of the many industrial uses of fluorspar, from metal work by ancient Romans to the processing of uranium by scientists seeking to perfect the atomic bomb. Preserving what is known about the industry by miners, managers, and museums, this detailed and fascinating pictorial history looks both above and below ground at fluorspar mining.
Download or read book Fluorite in Utah written by United States Geological Survey and published by CreateSpace. This book was released on 2014-05-17 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of Geological Survey Bulletin 1005. Unavailable since 1954, this publication was originally compiled by the USGS, State of Utah and U.S. Atomic Energy Commission and details the mining of fluorspar, also known as fluorite in the State of Utah. Included are details on the geology and history of fluorspar (fluorite) mining in Utah, including details on where this unique gem mineral may be found in the State of Utah. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface. As such, some type characters and images might suffer from slight imperfections or minor shadows in the page background.

Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
Download or read book Hydrothermal Uranothorite in Fluorite Breccias from the Blue Jay Mine Jamestown Boulder County Colorado written by George Phair and published by . This book was released on 1951 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of thin-section and heavy-mineral studies of fluorite breccias from Jamestown, Colo., the mineral thorite, variety uranothorite, was identified on the basis of chemical, spectrographic, optical, and X-ray data. This uranothorite is compared with uranothorite from South Westland, New Zealand, described by Hutton (1950), and with similar material from an Alaskan placer sample studied by the writers. These uranothorites are in turn contrasted with uranothorites described in the older literature all of which represent hydrated material. Thorium halos in fluorite are described, probably for the first time. The uranothorite associated with fluorite breccias is clearly of hydrothermal origin--unlike all previously described thorites and uranothorites with one very doubtful exception.

Download or read book Fluorspar Deposits Near Meyers Cove Lemhi County Idaho written by D. C. Cox and published by . This book was released on 1954 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluorspar deposits near Meyers Cove, Lemhi County, Idaho, are localized along three groups of shear zones: one group strikes northeast and dips steeply northwestward, another strikes northeast and dips gently northwestward, and the third strikes northwest and dips gently southwestward. The country rocks are tuffs and flows of the Casto volcanics of Permian (?) age and the Challis volcanics of late Oligocene or early Miocene age. The known deposits are in a belt about 3 miles long and 2 miles wide and crop out at altitudes between 5,100 feet and 7,200 feet above sea level. The principal vein minerals are fluorite, chalcedony, and barite. The fluorite occurs as lodes, crusts around fragments of rock, and replacements of fine breccia. The lodes range in size from veinlets to vein zones several hundred feet long and as much as 20 feet wide and contain ore that ranges in grade from 40 percent to 85 percent CaF2 ; the average grade is about 50 percent CaF2.
