Industrial minerals are used in a range of industrial applications including the manufacture of steel, chemicals, glass, fertilisers and fillers in pharmaceuticals and cosmetics, ceramics, plastics, paint, paper, and the treatment of gases and waste, etc. Industrial minerals include barites, bentonite, borates, clays, diatomite, feldspar, fluorspar, gypsum, limestone, silica sand, talc, and many others.

  • Wollastonite–A Versatile Industrial Mineral
    Industrial Minerals of the United States Wollastonite–A Versatile Industrial Mineral What is Wollastonite? Wollastonite is a chemically simple mineral named in honor of English mineralogist and chemist Sir W.H. Wollaston (1766–1828). It is composed of calcium (Ca) and silicon and oxygen (SiO2, silica) with the chemical formula CaSiO3. Although much wollastonite is relatively pure CaSiO3, it can contain some iron, magnesium, (Above and right) Hand specimens of manganese, aluminum, potassium, wollastonite showing acicular crystal clusters. sodium, or strontium substituting for calcium in the mineral structure.

    Proceedings of the Indiana Academy of Science Part II Addresses and Invited Papers Vol. 98 (1988) Speaker OF THE Year 63 SPEAKER OF THE YEAR ADDRESS—1988-89 INDUSTRIAL MINERALS—A CRITICAL KEY TO ECONOMIC DEVELOPMENT Haydn H. Murray Speaker of the Year Department of Geology Indiana University Bloomington, Indiana 47405 ABSTRACT: Industrial or non-metallic minerals are essen- tial to economic development. The value of industrial mineral production in the United States is over 3 times the value of metallic mineral production. In the developed countries of the world, the value of non-metallic mineral production exceeds the value of metallic mineral production. The development of a modern industrialized society requires quality and reason- ably priced industrial minerals in such industries as smelting of copper and iron, manufacturing cement, drilling oil wells, manufacturing ceramic materials, and a host of others. Be- cause transportation costs are high, most industrial minerals are not imported so a country or region must have a good raw material source. INTRODUCTION A precise inclusive definition for industrial minerals or non-metallic minerals is difficult because it includes many unrelated minerals that range from low priced materials such as sand and gravel to high priced materials like industrial dia- monds. The World Bank report (Noestaller, 1987) defines industrial minerals as comprising all non-metallic non-fuel minerals extracted and processed for industry end uses, some metallic minerals consumed in non-metallurgical applications,

    AP42 Section: 11.25 Reference: ~ Title: Clays, S. H. Patterson and H. H. Murray, Industrial Minerals And Rocks, Volume 1, Society Of Mining Engineers, New York, 1983. The term clay is somewhat ambiguous un- less specifically defined, because it is used in three ways: (I) as a diverse group of fine- grained minerals, (2) a5 a rock term, and (3) as a particle-size term. Actually, most persons using the term clay realize that it has several meanings, and in most instances they define it. As a rock term, clay is difficult to define be- cause of the wide variety of materials that com- ,me it; therefore, the definition must be gen- 'eral. Clay is a natural earthy, fine-grained ma- Iterial composed largely of a group of crystalline ;minerals known as the clay minerals. These minerals are hydrous silicates composed mainly of silica, alumina, and water. Several of these minerals also contain appreciable quantities of iron, alkalies, and alkaline earths. Many defini- tions state that a clay is plastic when wet. Most clay materials do have this property, but some clays are not plastic; for exaniple, halloysite and flint clay. As a particle-size term, clay is used for the category that includes the smallest particles. The maximum-size particles in the clay-size grade are defined differently on various grade scales. Soil imestigators and mineralogists gen- erally use 2 micrometers as the maximum size, whereas the widely used scale by Wentworth (1922) defines clay as material finer than ap proximately 4 micrometers. Some authorities find it convenient to'use the term clay'for any fine-grained, natural, earthy, argillaceous material (Grim.

    Industrial Minerals-Mines, Quarries, and General Resources in Kansas 2008 Lawrence L. Brady Kansas Geological Survey 1930 Constant Avenue Lawrence, Kansas 66047 Telephone (785) 864-2159 Fax (785) 864-5317 E-mail lbrady@ kgs.k u.edu Kansas Geological Survey Open-File Report 2016-24 ABSTRACT Industrial mineral production in Kansas based on tonnage mainly involves those commodities that are important to the construction industry. Among those commodities with large tonnage are sand and gravel and stone—both crushed and dimension, mainly limestone but also with a limited amount of sandstone. Sand and gravel are obtained primarily from pits in western Kansas and from pits and dredging in rivers and floodplains in the central and eastern part of the state. Crushed stone for aggregates and for use in cement production is mainly from limestone units of Pennsylvanian age in eastern Kansas, and the dimension stone is now cut from Lower Permian limestone units. Outstanding buildings in the past were also constructed from limestone rocks from Middle and Upper Pennsylvanian and Upper Cretaceous limestone units. Clay and shale from Pennsylvanian and Cretaceous units are used for manufacture of structural clay products, brick, and lightweight aggregate and in Portland and masonry cement manufacture. Salt is a major industrial mineral important to the state. It is produced from the thick Hutchinson Salt Member in the Lower Permian Wellington Formation that is present in the subsurface in a large part of central Kansas. The salt is mined by room-and-pillar methods at three locations, and salt is also produced by solution mining from four different brine fields.

  • Industrial Minerals - Towards a Future Growth
    NGU-BULL 436, 2000 - PAGE 7 Industrial minerals - towards a future growth TOR ARNE KARLSEN & BRIAN STURT† Karlsen, T.A. & Sturt, B.A., 2000: Industrial minerals - towards a future growth. Norges geologiske undersøkelse 436, 7-13. The Norwegian mineral industry has shown pronounced growth in recent years, and production and export of industrial minerals (sensu stricto), aggregates and dimension stone have all increased, whilst the production and export of metallic ore has decreased. This is a trend that has been going on for many years. The trend for industrial minerals is to a large degree related to the increased production of calcium carbonate slurry for paper. The total production value of Norwegian industrial minerals reached around 2370 mill. NOK in 1997. In terms of volume around half of the produced industrial minerals are exported. The export value in 1997 was 2260 mill. NOK – including some minor imported minerals, an increase of 20.5 % over 1996. This figure can also be compared to a total export value of approximately 700 mill. NOK in 1989. An understanding of the real value of domestically produced industrial minerals is not gained purely from production value and export figures of the minerals. In fact, domestically produced industrial minerals form the basis and are important for many other industries, including the production of ferrosilicon, Mg-metal, TiO2-pigment, paints, fertilisers, chemicals and cement. Together with the production of aluminium, paper and Si-metal, which to a large degree is based on imported raw materials, these industries have a total annual turnover probably in the order of 40,000 mill.

  • Industrial Minerals and Rocks in the 21St Century
    Industrial Minerals and Rocks in the 21st Century Milos Kuzvart Charles University, Prague NONMETALLICS: DEFINITION, CLASSIFICATION, OCCURENCE, ORIGIN, UTILIZATION The term 'industrial mineral' is not defined so strictly as the term 'ore' which is mostly a source of metal, or as that of 'fossil fuel' (coal, oil, natural gas), which is predominantly a source of energy. In both the latter cases the characteristic feature is the chemistry of the ore (besides the content of impurities, dressability, etc.) or fuel (besides the content of dirt bands, sulfur, etc.). The characteristic features of industrial minerals, however, líe in their physical properties (e.g., fibrosity of asbestos, insulatory properties of mica, the high specific gravity of barite). In this artiele raw materials of several types are considered under the term "industrial mineral s and rocks": 1. raw materials that are used in industry in variously prepared forms as minerals (e.g., talc, asbestos, diamond) or rocks (diatomite, bentonite, ochre); 2. raw material s that serve as a source of non-metallic elements (ftuorite for ftuori­ ne, apatite for phosphorus) or their simple compounds (e.g., borates for H3B03 or B 20 3); 3. raw materials of non-metallic habit that are source of metals, and also of their com­ pounds employed in other than metallurgical industries (e.g., beryl as a source of BeO, magnesite of MgO, bauxite or Al-rich laterite as a source of Alz03; all these three oxides are refractory materials); 4. building material s (rocks for aggregate, together with gravel and sand for concrete, decorative stone and roofing slate, limestone for cement and lime, brickloam).

  • Virginia's Minerals & Energy Resources
    Chapter 5: Virginia's Minerals & Energy Resources Part 1: Mineral Resources Minerals are the raw materials that support much of modern life - everything from transportation to the growing of food. Chemists, all sorts of manufacturers, farmers and a variety of artisans depend upon minerals to conduct business. Virginia's mineral deposits are vast and varied, but coal remains most important to the Commonwealth. Measuring Virginia's Geologic Wealth In Virginia the estimated dollar value of mineral resources produced has increased almost sevenfold in the past 44 years, from $545 million in 1973 to $3.7 billion in 2012. Yet this figure tells only a small part of the story of the importance of the state's geologic resources. Soil and water, two valuable resources and without which there would be no life, are not included. Nor are parks and other scenic and recreational areas, most of which owe their natural beauty to the geology of their location. The Blue Ridge mountains, the caverns and caves and the Shenandoah Valley are only a few examples. Geology and Mineral Exploration The science of geology is the study of the earth and its history and the processes and forces which are constantly at work changing the face of the earth. It is such a broad subject that it has been divided into a number of individual sciences: geophysics and oceanography for example. Geologists try to explain how the earth was formed and has changed through time. Many industries rely upon a geologist to locate new sources of raw materials. Through the use of field mapping and specialized investigative techniques, geologists discover and develop such resources as petroleum, iron ore, copper, limestone and sulfur.
