Abstract:

Clays are materials consisting of clay minerals and non-clay minerals. Some applications allow to use raw clay others require to separate clay minerals from non-clay minerals. Clay mineral fraction is considered to be a nanofraction. Description and characterization of 3 different Latvian clay nanosized minerals from 3 different geological periods (clay Liepa from Devonian period, clay Vadakste from Triassic period and clay Apriki from Quaternary period) are summarized. The main mineral in these clays is illite, however the presence of kaolinite is observed and its quantity depends on geologic

Abstract:

In the mines of Guanajuato, Mexico, when miners drill and dynamite for metallic ore, they dislodge other substances. Among these are elements and compounds known as “minerals,” sold and collected in their own right as scientific specimens or aesthetic collectibles. These minerals often fetch thousands of dollars at mineral shows and collector showrooms in Tucson, Arizona and other mineral collecting hubs. In this process, minerals move from byproducts and even waste to highly valued commodities in their own right.

AbstractThe application of Raman spectroscopy to the study of the mixed cationic Pb-Cu and Pb-Cu-Ag minerals: boleite, cumengeite and diaboleite has enabled their molecular structures to be compared. Each of these three minerals shows different hydroxyl-stretching vibrational patterns, but some similarity exists in the Raman spectra of the hydroxyl-deformation modes. The low-wavenumber region is characterized by the bands assigned to the cation-chloride stretching and bending modes. Phosgenite is also a mixed chloride-carbonate mineral and a comparison is made with the molecular structure of t

AbstractBredigite is a constituent of the very high-temperature, low-pressure, exomorphic suite of Carneal, Co. Antrim. Although this mineral is very rare in nature, it is an important constituent of some slags and cement clinkers but there has been much controversy about its nature, most of the evidence having come from artificial materials. Chemical analysis of the Carneal mineral shows it to be remarkably similar to that from the type locality, Scawt Hill (also analysed here), and that it is an individual mineral species of generalized ionic composition (Ca,Na)14(Mg,Fe2+Fe3+Mn)2(Si,P)8O32.

Abstract:

Activation of coal gangue from Yixing was done by the method of addition of calcium during calcination. Structural characteristic and cementitious properties of activated samples were analyzed. And then hydration degree of activated coal gangue cement was studied. The results show that: thermally and chemically added-calcium composite activation method can improve the activity of coal gangue. At 1050°C, more effective silicate minerals may be in activated samples, with which cement system may have a higher degree of hydration. infra-red(IR) spectra shows that large number of new mineral peaks

Abstract:

Samples of mafic intrusive rock were analyzed for their mineralogical and chemical properties. The textural relationship was studied using the petrographic microscope, elemental composition of minerals was determined using the Electron Microprobe and the whole rock chemical analysis was done using the XRF and ICP-MS. The following minerals were observed in order of abundance; pyroxene, amphibole, plagioclase, biotite, opaque minerals, quartz and chlorite, with apatite and zircon occurring as accessory mineral. Two types of pyroxenes were observed; orthopyroxene (hypersthene) and clinopyroxene.

Plants are the cheapest and indispensable constituents of human diets supplying the body nutrients (carbohydrates, protein, fats, amino acids, vitamins) necessary for growth and body development. Therefore, this work was designed to examine the proximate and mineral composition of Pentadiplandra brazzeana stem bark (PBSB). Proximate composition of PBSB revealed the presence of 8.75 % moisture, 91.25 % dry matter, 6.43 % crude protein, 41.03 % crude fibre, 5.70 % ether extract, 12.11 % ash, 17.82 (g/100 g) carbohydrates, 0.47 % total reducing sugar and 632.2 Kj/100g energy respectively.

Garnet solid solution is dominated by grossular-andradite series, which demonstrates a significant degree of hydration, mainly for grossular rich garnet cores. Garnet is locally enriched in TiO2 (up to 13 wt%), possibly indic

It shows that heavy mineral contents, species, and compositions vary in different grain sizes. Distribution curve of heavy mineral concentration (HMC) and particle size frequency curve are in normal distribution. In most samples, the size fraction of 4.5–5.0 Φ contains the maximum HMC (18% on average). Heavy mineral assemblages of the Yellow River are featured by amphibole + epidote + limonite + garnet.

Also, the mineral composition of each component was analyzed by electron microscopy. The metal minerals were mainly concentrated in the mineral components. Besides, the electron probe microanalysis shows that the Pt content in the minerals of fly ash was significantly correlated
