Mineralogical characteristics of ceramics
2012Ten samples of recent ceramics’ fragments were analyzed using XRPD method. The ceramics are variably coloured as well as multicoloured. Two fragments are completely brownish-red ; two fragments are red with a thin black film on the one side and six fragments are black in the middle and red on the outer sides.

Genesis and Mineralogical Characteristics
2015Soils of Iceland form in volcanic materials deposited by aeolian processes and as tephra deposited during volcanic eruptions. The surface is steadily rising, but the tephra materials weather readily to form clay minerals characteristic of volcanic areas: allophane of low Al/Si ratio, ferrihydrite and imogolite .

Mineralogical characteristics and treatment of refractory gold ores
Minerals Engineering, 1989Abstract Refractory gold ores and concentrates are characterised by low gold recoveries and high cyanide consumptions when subjected to direct cyanide leaching. Therefore an oxidation pretreatment step is required before cyanidation that will break up the sulphide lattice and render gold particles accessible to cyanide ions.

Relating mineralogical and textural characteristics to flotation behaviour
Minerals Engineering, 2015Abstract Having knowledge of the ore mineralogy and texture can provide valuable information for effective design of a concentrator flowsheet. Specifically, these characteristics help in setting the appropriate grind size to achieve liberation and minimise overgrinding, and assist in identifying suitable flotation parameters to achieve optimum ...

Textural and mineralogical characteristics of SPM in coal mines
International Journal of Surface Mining, Reclamation and Environment, 1997ABSTRACT The ultimate goal of air pollution assessment and control effort is to mitigate the effect of pollutants on environment. The effects may be on health, various other biological systems, and physical quality of environment. The severity of impact of airborned suspended particulate matter may depends upon its physico-chemical properties. Opencast

[Mineralogical and spectral characteristics of copper pectolite].
Guang pu xue yu guang pu fen xi = Guang pu, 2015Copper pectolite, a type of pectolite with blue stripes, is a rare gem material with a great market prospect. Mineralogy and genesis were investigated using X-ray diffraction (XRD), Fourier infrared absorption spectroscopy (FTIR), Raman spectroscopy (Raman), scanning electron microscopes (SEM) and ultraviolet-visible spectrometer(UV-VIS) to understand ...

Mineralogical characteristics of electric arc furnace dusts
JOM, 1991Reflected light microscopy can contribute important information regarding the mineralogy, mineral abundance, internal textures, sizes and shapes of particles in electric arc furnace (EAF) dusts. Scanning electron microscopy-energy dispersive spectroscopy and electron microprobe analysis are useful to determine the chemical compositions of the specific ...

Mineralogical and chemical characteristics of Croatian bentonites
2012In Croatia several bentonite deposits have already been described. The aim of the present study was to obtain additional information on mineralogical and chemical characteristics of bentonites from several deposits: Maovice-Štikovo (Middle Dalmatia, S Croatia), Gornja Jelenska (Moslavina, N Croatia), Bednja and Poljanska Luka (Hrvatsko Zagorje, NW ...

Chemical and Mineralogical Characteristics of Eutrophic Lake Sediments
Soil Science Society of America Journal, 1969Abstract Detailed chemical and mineralogical analyses of the sediments of an eutrophic lake revealed that most of the characteristics usually associated with high productivity increased considerably with increasing depth of water.

Acidic Properties of Soils as Influenced by Their Mineralogical Characteristics
Soil Science Society of America Journal, 1965Abstract A number of soils with their clays predominantly composed of biotite, hydrobiotite, and vermiculite or predominantly montmorillonite were treated with 0.1 n HCl, washed free of excess acid, and then air‐dried.
