In addition, minor amounts of magnetite, feldspar, biotite, lizardite, and pyroxene, as well as trace amounts of amphibole, quartz, and chlorite, were also determined and identified in this sample.
In order to compare the behavior of the tailings with the residual soils, soil samples were also collected from two predominant classes in the basin, chosen on the basis of their distinct pedological characteristics, represented by red-yellow latosols and cambisols (Fig. 3).In Fig. 3, the sampling points are highlighted in relation to the river basin impacted by the dam …

Biotite, usually dark green, brown, or black, has a pale brown color under plane-polarized light in this sample. It exhibits high interference colors in cross-polar light just as muscovite, but has a lower birefringence than muscovite. Biotite shows parallel extinction in cross polarized light, and has perfect cleavage in one direction.
This research work aims at synthesizing muscovite through a straightforward and direct wet thermal oxidation of an ash sample produced from biotite-rich coal tailings. For this …

Initial ... magnetite, hematite, and biotite. The chemical composition analysis using AAS of skarn ore shows content of 0.66% Sn, 33.16% Fe, and 10. ...
Iron ore tailings. A number of representative iron ore tailing samples were acquired from different locations of the dry tailing disposal areas (cf. Fig. 2).As illustrated in Fig. 3, the tailings were loosely dumped as piles; thus, their sampling did not necessitate any particular practice and merely involved filling bags with a hand shovel.A total number of 16 tailing …
XRD pattern for the as-received sample is shown in Fig. 2 from which high-intensity peaks for quart can be observed. The other XRD peaks in the material are biotite (K(Mg,Fe) 3 AlSi 3 O10(F,OH) 2) and orthoclase (KAlSi 3 O 8). The intensity peaks for copper-bearing minerals could not be observed as they are below the detection limit of the ...
Outcrops of biotite granite and diorites were mapped as the main lithological units. Fourteen (14) water samples ... rock piles and tailing dams cause changes in the water quality and quantity. Water ... The field equipment used during geological field work and sampling programme include; geological hammer, geological compass, sampling bags ...
Especially, Bangka Island is located in a tropical area with medium rainfall, around 2500 mm/year (Yusoff et al., 2013). This island was intruded by granite pluton with an altitude between 0 ->400 ...

The samples with a particle size of −300 + 0 µm contained smaller amounts of biotite than the starting sample (maximal 7.71%). In fractions with a particle size of +200 µm, significantly larger quantities of this mineral were detected (~12% for the fraction −400 + 300 µm and ~15% for the fraction +400 µm). ...
In addition to traditional geotechnical samplers, ConeTec has designed several specialty sampling systems specific to mine tailings applications. These samplers are designed to collect representative samples in tailings materials ranging from process water, to fluid slimes, to liquefiable sandy silt, to dense beach and dyke deposits.
In a sample of schist, biotite's flat, shiny sheets align in parallel, imparting a distinct foliation to the rock. This alignment occurs due to directional pressure during metamorphism. The role of biotite extends beyond physical rock characteristics. Its ability to include trace elements like titanium and vanadium can indicate specific ...
