The foundation is probably concrete (limestone, clay, shale, gTpsum, and aggregate mining). The exterior walls may be made of brick (clay mining) or stone (dimension stone mining). The insulation in the walls may be glass wool (silica, feldspar, and trona mining) or expanded vermiculite (vermiculite mining). The interior walls are usually wallboard (gypsum mining). The lumber in the structure will be fastened with nails and screws (iron ore mining and zinc mining). If the roof is covered with asphalt shingles, the filler in the shingles is from a variety of colored silicate minerals from mining. Your fireplace is probably of brick or stone, lined with a steel box (iron ore mining). Your sewer piping is made of clay or iron pipe (clay mining or iron ore mining). Your water pipe is of iron or copper pipe (iron ore mining and copper mining). Your eleetrical wiring is of eopper or aluminum (copper mining or bauxite mining). Your sanitary faeilities are made of porcelain (clay mining). Your plumbing fixtures are made of brass (copper and zinc mining), or stainless steel (nickel and chrome mining). Your gutters are of galvanized steel (iron ore mining and zinc mining). The paint is manufactured with mineral fillers and pigments (from minerals obtained by mining). Your windows are made of glass (trona, siliea and feldspar mining). Your door knobs, loeks, and hinges are of brass or steel (copper, zinc, and iron ore mining). And finally, your mortgage is written on paper made from wood or cloth fibers, but fibers filled with elay (clay mining). l Modified fuom M'i,ning Engi,neeri,W, January 1976.

MINERALS FOR VIRGINIA Harry W. Webb and John P. Moore INTRODUCTION Virginia is rich in minerals--a natural wealth. The welfare and economic progress of the Com- monwealth has been largely dependent upon the discovery and production of rock and mineral resources since Colonial days. Mineral production in North America began with the settlement at Jamestown, where iron was produced'as early as 1609. The types and amounts of minerals used have varied since then, largely in response to the eco- nomic development of the State and Nation. Today a variety of natural rock materials are extracted from mines, pits, and quanies across the State for many uses (Map in Pocket). The purpose of this report is to describe industrial mineral develop- ment of the State, exclusive of fuels and metals, in terms understandable to the general reader. Virginia has a large and diverse mineral indus- Figure 1. Quarry operation with drilling rig pre- try.

All of Virginia's counties have resources from which mineral commodities can be produced. There are some counties, however, in which minerals are not being extracted today. Production of industrial minerals in Virginia is a multimillion-dollar-a-year industry and in 1983, was valued at about $289,344,000. Many raw mineral materials are mined from quarries and pits (Figures 1 and 2). These openings in the ground mean different things to a wide variety of people. To consumers,

    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.

  • CASE STUDY Methane Recovery at Non-Coal Mines
    CASE STUDY Methane Recovery at Non-coal Mines Background Existing methane recovery projects at non-coal mines reduce greenhouse gas (GHG) emissions by up to 3 million tons of carbon dioxide equivalent (CO₂e). Although methane emissions are generally associated with coal mines, methane is also found in salt, potash, trona, diamond, gold, base metals, and lead mines throughout the world. Many of these deposits are located adjacent to hydrocarbon (e.g., coal and oil) deposits where methane originates. Consequently, during the process of mining non-coal deposits, methane may be released. Overview of Methane Recovery Projects Beatrix Gold Mine, South Africa Promethium Carbon, a carbon and climate change advisory firm, has developed a project to capture and use methane from the Beatrix Gold Mine in Free State, South Africa (see box).

    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.

  • Remarks on Different Methods for Analyzing Trona and Soda Samples
    REMARKS ON DIFFERENT METHODS FOR ANALYZING TRONA AND SODA SAMPLES Gülay ATAMAN*; Süheyla TUNCER* and Nurgün GÜNGÖR* ABSTRACT. — Trona is one of the natural forms of sodium carbonate minerals. It is well known as «sesque carbonate», «urao» or «trona» in the chemical literature, and the chemical formula of the compound is [Na2CO3.NaHCO3.2H2O]. The aim of this work is to adapt the standard methods for the analysis of trona samples, considering the inter- ferences arising from silicates and other minerals found together with trona samples. In order to reduce the experimen- tal errors, the analyses used for the determination of trona samples have been revised. The experimental results using potentiometric titration, AgNO3 external indicator and BaCl2 titration methods have been compared to theoretical results using statistical evaluations. 95 % confidence level, which is commonly used by analytical chemists, was employed as the basis of evaluation, R values, Student's t calculated at 95 % confidence level of 7 trona samples from Beypazarı, Student's t tabulated for the percentages of Na2CO3, were found to be 0.008 in BaCl2 method, 3.25 for AgNO3 external indicator method and 3.26 for potentiometric method; for the percentages of NaHCO3 the same values are 0.59 for BaCl2 method, 2.83 for AgNO3 external indicator method and 3.59 for potentiometric method. Systematic error is indicated when R> 1. In addi- tion to quantitative analysis of trona samples, qualitative XRD analyses have been routinely performed for each sample and the results were found to be in good agreement. INTRODUCTION Trona is a naturally occuring from of sodium carbonate minerals.

  • Industrial Minerals-Mines, Quarries, and General Resources in Kansas 2008
    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.
