  • Structure and Composition OXIDATION ZONE
    OXIDATION ZONE Structure and Composition The first scanty information on the oxidation zone of the Rubtsovskoe deposit was obtained as a result of drilling in the early 1970s. Three major subzones were distinguished downward: (1) a leached oxidized ore zone largely composed of iron hydroxides and kaolinite; (2) a secondary oxide enrichment subzone with cuprite, native copper, malachite, azurite, cerus - site; and (3) a secondary sulfide enrichment subzone (that transitions to an underlying zone of mixed ores) with chalcocite and covellite (Stroitelev et al. , 1996). As a result of our observation in underground workings, the structure, min - eralogy, and genetic features of the oxidation zone of the deposit were spec - ified substantially. The top of the orebody is supergene altered to the highest degree at the WSW flank, where it is located higher in altitude. The upper boundary of the orebody gently plunges ENE and the oxidation zone (we do not discuss the mixed ores) gradually pinches out; the oxidation zone extends along the strike of the orebody for approximately 300 m. In the WSW part of the ore - body, the oxidized ores occur in the altitude interval from +137–138 to +163 m. The lower boundary of the oxidized ores rise toward the ESE and the main part of the oxidation zone occurs in the range of +144–145 to +153–157 m. The oxidized part of the orebody varies from 2 to 8 m in thickness, reaching 15–17 m in swells and occasionally more than 20 m. Both underlying and overlapping rocks are dominated by clayey minerals; these are wall-rock argillaceous alterations, frequently altered as a result of ore oxidation especially adjacent to the contact of the orebody.

  • Addition of a Grignard Reagent to an Ester: Formation of a Tertiary Alcohol
    Addition of a Grignard Reagent to an Ester: Formation of a Tertiary Alcohol Introduction: Grignard reagents are important and versatile reagents in organic chemistry. In this experiment, you will prepare a Grignard reagent and react it with an ester to prepare a tertiary alcohol. Specifically, in this reaction you will prepare phenyl magnesium bromide from bromobenzene and magnesium metal and then react it with methyl benzoate to prepare triphenylmethanol (Figure 1). In this reaction, two equivalents of phenylmagnesium bromide add to methyl benzoate. Note: Grignard reagents are sensitive to water. ALL glassware must be completely clean and dry. Reagents have been stored over molecular sieves to keep them dry in storage, but you should also keep containers closed as much as possible. Finally, water in the air can also react with the Grignard reagents over time. To successfully prepare triphenylmethanol in this experiment, you will need to be well organized and not take too much time between steps. Figure 1. O 1) Me O OH Br Mg MgBr THF + 2) H3O triphenylmethanol Mechanism: The formation of Grignard reagents from aryl halides is a complex mechanism, which takes place on the surface of the magnesium metal. You do not need to concern yourself with the details of this step of the mechanism. Figure 2.

  • Grignard Reaction: Synthesis of Triphenylmethanol
    *NOTE: Grignard reactions are very moisture sensitive, so all the glassware in the reaction (excluding the work-up) should be dried in an oven with a temperature of > 100oC overnight. The following items require oven drying. They should be placed in a 150mL beaker, all labeled with a permanent marker. 1. 5mL conical vial (AKA: Distillation receiver). 2. Magnetic spin vane. 3. Claisen head. 4. Three Pasteur pipettes. 5. Two 1-dram vials (Caps EXCLUDED). 6. One 2-dram vial (Caps EXCLUDED). 7. Glass stirring rod 8. Adaptor (19/22.14/20) Grignard Reaction: Synthesis of Triphenylmethanol Pre-Lab: In the “equations” section, besides the main equations, also: 1) draw the equation for the production of the byproduct, Biphenyl. 2) what other byproduct might occur in the reaction? Why? In the “observation” section, draw data tables in the corresponding places, each with 2 columns -- one for “prediction” (by answering the following questions) and one for actual drops or observation. 1) How many drops of bromobenzene should you add? 2) How many drops of ether will you add to flask 2? 3) 100 µL is approximately how many drops? 4) What are the four signs of a chemical reaction? (Think back to Chem. 110) 5) How do the signs of a chemical reaction apply to this lab? The Grignard reaction is a useful synthetic procedure for forming new carbon- carbon bonds. This organometallic chemical reaction involves alkyl- or aryl-magnesium halides, known as Grignard 1 reagents. Grignard reagents are formed via the action of an alkyl or aryl halide on magnesium metal.

Spectrochimica Acta 62(1):pp. 181-188. Copyright 2005 Elsevier Abstract The phosphate minerals hannayite, newberyite and struvite have been studied by Raman spectroscopy using a thermal stage. Hannayite and newberyite are -1 characterised by an intense band at around 980 cm assigned to the ν1 symmetric stretching vibration of the HPO4 units. In contrast the symmetric stretching mode is -1 observed at 942 cm for struvite. The Raman spectra are characterised by multiple ν3 antisymmetric stretching bands and ν2 and ν4 bending modes indicating strong distortion of the HPO4 and PO4 units. Hannayite and newberyite are defined by bands -1 at 3382 and 3350 cm attributed to HOPO3 vibrations and hannayite and struvite by + bands at 2990, 2973 and 2874 assigned to NH4 bands. Raman spectroscopy has proven most useful for the analysis of these ‘cave’ minerals where complex paragenetic relationships exist between the minerals. Keywords: hannayite, newberryite, struvite, phosphate, Raman spectroscopy Introduction Interest in struvite formation also comes from the formation in urinary tracts and kidneys [1-6].

  • The Minerals and Rocks of the Earth 5A: the Minerals- Special Mineralogy
    Lesson 5 cont’d: The Minerals and Rocks of the Earth 5a: The minerals- special mineralogy A. M. C. Şengör In the previous lectures concerning the materials of the earth, we studied the most important silicates. We did so, because they make up more than 80% of our planet. We said, if we know them, we know much about our planet. However, on the surface or near-surface areas of the earth 75% is covered by sedimentary rocks, almost 1/3 of which are not silicates. These are the carbonate rocks such as limestones, dolomites (Americans call them dolostones, which is inappropriate, because dolomite is the name of a person {Dolomieu}, after which the mineral dolomite, the rock dolomite and the Dolomite Mountains in Italy have been named; it is like calling the Dolomite Mountains Dolo Mountains!). Another important category of rocks, including parts of the carbonates, are the evaporites including halides and sulfates. So we need to look at the minerals forming these rocks too. Some of the iron oxides are important, because they are magnetic and impart magnetic properties on rocks. Some hydroxides are important weathering products. This final part of Lesson 5 will be devoted to a description of the most important of the carbonate, sulfate, halide and the iron oxide minerals, although they play a very little rôle in the total earth volume. Despite that, they play a critical rôle on the surface of the earth and some of them are also major climate controllers. The carbonate minerals are those containing the carbonate ion -2 CO3 The are divided into the following classes: 1.

ABSTRACT Minerals containing cobalt as an essential element display systematic trends in their diversity and distribution. We employ data for 66 approved Co mineral species (as tabulated by the official mineral list of the International Mineralogical Association, http://rruff.info/ima, as of 1 March 2016), represent- ing 3554 mineral species-locality pairs (www.mindat.org and other sources, as of 1 March 2016). We find that cobalt-containing mineral species, for which 20% are known at only one locality and more than half are known from five or fewer localities, conform to a Large Number of Rare Events (LNRE) distribution. Our model predicts that at least 81 Co minerals exist in Earth’s crust today, indicating that at least 15 species have yet to be discovered—a minimum estimate because it assumes that new minerals will be found only using the same methods as in the past. Numerous additional cobalt miner- als likely await discovery using micro-analytical methods.

  • The Origins of Color in Minerals Four Distinct Physical Theories
    American Mineralogist, Volume 63. pages 219-229, 1978 The origins of color in minerals KURT NASSAU Bell Laboratories Murray Hill, New Jersey 07974 Abstract Four formalisms are outlined. Crystal field theory explains the color as well as the fluores- cence in transition-metal-containing minerals such as azurite and ruby. The trap concept, as part of crystal field theory, explains the varying stability of electron and hole color centers with respect to light or heat bleaching, as well as phenomena such as thermoluminescence. The molecular orbital formalism explains the color of charge transfer minerals such as blue sapphire and crocoite involving metals, as well as the nonmetal-involving colors in lazurite, graphite and organically colored minerals. Band theory explains the colors of metallic minerals; the color range black-red-orange- yellow-colorless in minerals such as galena, proustite, greenockite, diamond, as well as the impurity-caused yellow and blue colors in diamond. Lastly, there are the well-known pseudo- chromatic colors explained by physical optics involving dispersion, scattering, interference, and diffraction.

  • 1 Revision 1 Single-Crystal Elastic Properties of Minerals and Related
    Revision 1 Single-Crystal Elastic Properties of Minerals and Related Materials with Cubic Symmetry Thomas S. Duffy Department of Geosciences Princeton University Abstract The single-crystal elastic moduli of minerals and related materials with cubic symmetry have been collected and evaluated. The compiled dataset covers measurements made over an approximately seventy year period and consists of 206 compositions. More than 80% of the database is comprised of silicates, oxides, and halides, and approximately 90% of the entries correspond to one of six crystal structures (garnet, rocksalt, spinel, perovskite, sphalerite, and fluorite). Primary data recorded are the composition of each material, its crystal structure, density, and the three independent nonzero adiabatic elastic moduli (C11, C12, and C44). From these, a variety of additional elastic and acoustic properties are calculated and compiled, including polycrystalline aggregate elastic properties, sound velocities, and anisotropy factors. The database is used to evaluate trends in cubic mineral elasticity through consideration of normalized elastic moduli (Blackman diagrams) and the Cauchy pressure. The elastic anisotropy and auxetic behavior of these materials are also examined. Compilations of single-crystal elastic moduli provide a useful tool for investigation structure-property relationships of minerals. 1 Introduction The elastic moduli are among the most fundamental and important properties of minerals (Anderson et al. 1968). They are central to understanding mechanical behavior and have applications across many disciplines of the geosciences. They control the stress-strain relationship under elastic loading and are relevant to understanding strength, hardness, brittle/ductile behavior, damage tolerance, and mechanical stability. Elastic moduli govern the propagation of elastic waves and hence are essential to the interpretation of seismic data, including seismic anisotropy in the crust and mantle (Bass et al.

Copper by exothermal reaction between bromides and water vapour. A protocol to test the corrosion of surrounding A. Carbon steel −1 materials is discussed in the case of SrBr2 contacting copper or steel. Corrosion depth > 1 mm y is found for B. Weight loss steel in conditions where the salt remains mostly solid, due to a reaction between SrBr2 and atmospheric CO2 B. XRD that produces HBr. Temperature and the dissolution of the salt (deliquescence) also play a key role. B. Cyclic voltammetry Potentiodynamic tests, the limitations of which are discussed, corroborate the salt degradation in the case of C. Reactor conditions steel. 1. Introduction Since the late eighties, several papers have been dedicated to the corrosion problem in the case of PCMs, with tests focused on the While electrical power storage is becoming widespread through melting process or the liquid phase [21–34], and quite often in organic applications like electrical vehicles, thermal energy storage still needs compounds [30,35,36].
