This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manganese nodules were first discovered on the ocean floor 160 miles south-west of the Canary Islands on February 18, 1803, during the first complex oceano logical cruise of the Challenger. They surprised researchers by their unusual shape and also by their unusual chemical composition; nevertheless for many years after wards, they were considered merely as one of Nature's exotic marine tricks. After the Secpnd World War, a comprehensive investigation of the World Ocean started, and new data were obtained on a wide distribution of manganese nodules and their polymetallic composition, that made scientists consider nodules as one of the major characteristics of the deep oceanic zone. Recently, meaning since the 1960's, nodules have been recognized as a potential ore source, investigation of which is stimulated by the progressive depletion of land-based mineral resources. Several generations of scientists from various countries have contributed to the problem of exploration of manganese nodules on the ocean floor. Though the problem has been posed, it has not been solved yet because it required, in its turn, a scrutiny of some fundamental aspects such as composition, nature, accretion r'ate of nodules and retrieval of nodule fields. These problems have been discussed in thousands of papers and larger publications; see, in particulare, Mero, 1965; Horn, 1972; Morgenstein, 1973; Bezrukov, 1976; Glasby, 1977; Bischoff and Piper, 1979; Lalou, 1979; Manganese nodules, 1979; Varentsov, 1980; Cronan, 1980; Manganese nodules . . . , 1984, 1986.

Download or read book Manganese Mineralization written by Keith Nicholson and published by Geological Society of London. This book was released on 1997 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manganese mineralization is diverse in occurence, origin, mineralogy and geochemistry. This volume includes a review of the range of terrestrial Mn deposits and their relative abundance through geological time. Experimental and modelling approaches to Mn geochemistry and mineralogy can further aid our understanding of the formational and depositational processes involved and thereby our interpretation of deposit metallogenesis.

This book was released on 2013-03-09 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major part of the world's high grade industrial manganese ore is being mined in supergene deposits. This book represents the first attempt to bring together not only academic but also commercial data on all aspects of the geochemistry of formation of supergene manganese ores. It is a distinctive account of the geology, geochemistry, mineralogy, experimental modelling studies, mechanisms of formation processes and geochemical evolution through geological time of manganese ores for all types of supergene deposits. Special emphasis is placed on the general geochemical model of supergene manganese ore formation, which can be applied in geochemical exploration. Despite the fact that supergene manganese ores have been used by mankind since the early centuries, it is only during the last decade that a comprehensive understanding of the nature of geochemical processes of formation of these deposits has become available and their potential as an economic resource has been recognized against other genetical types of manganese accumulations. Audience: This substantial and comprehensive volume is of interest to economic geologists, mining engineers, geochemists, mineralogists and other specialized geoscientists.

This book was released on 2013-03-08 with total page 839 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep-sea manganese nodules, once an obscure scientific curios ity, have, in the brief span of two decades, become a potential mineral resource of major importance. Nodules that cover the sea floor of the tropical North Pacific may represent a vast ore de posit of manganese, nickel, cobalt, and copper. Modern technology has apparently surmounted the incredible problem of recovering nodules in water depths of 5000 meters and the extraction of metals from the complex chemical nodule matrix is a reality. Both the recovery and the extraction appear to be economically feasible. Exploitation of this resource is, however, hindered more by the lack of an international legal structure allowing for recognition of mining sites and exploitation rights, than by any other factor. Often, when a mineral deposit becomes identified as an ex ploitable resource, scientific study burgeons. Interest in the nature and genesis of the deposit increases and much is learned from large scale exploration. The case is self evident for petrol eum and ore deposits on land. The study of manganese nodules is just now entering this phase. What was the esoteric field of a few scientists has become the subject of active exploration and research by most of the industrialized nations. Unfortunately for our general understanding of manganese nodules, exploration results remain largely proprietary. However, scientific study has greatly increased and the results are becoming widely available.
