Biotite, glauconite, ferrorichterite require four latent variables. The concentration of quartz and Fe-oxides are estimated using two latent variables and stilpnomelane needs seven. As explained in the previous section, the model is trained using the average of three spectra per sample and validated by leave-one-out cross validation technique.
No significant changes in the crystalline phases dependent on the tailings' sampling points were found in the XRD patterns, as shown, ... microcline, biotite, or …

The sampling points are illustrated in Fig. 2. All profile tailings and rock samples gathered were bagged in double-zipped plastic bags, kept in plastic containers and prepared for delivery to the labs. Each tailing and rock sample, amounting to approximately 300 g, underwent a 5-day drying process in a 40 °C oven.
A complete characterization of the copper tailing sample was carried out as chemical and mineralogical composition and size distribution. The analytical procedures are depicted in Table 1. ...

Map of actual sampling from bund wall of tailing pond. 1. OBJECT OF RESEARCH The initial raw product for investigations was the material from the tailing pond of gold processing plant of one enterprise in the Krasnoyarsk Territory, where the tailings of oxidized, mixed, primary sulfide gold ores have been accumulated over the years of operation.
Detailed field sampling and laboratory methods were used to characterize the hydraulic properties of the tailings, their bulk chemistry, mineralogy, pore water and effluent …
X-ray diffraction analysis revealed that the major phases in the as-received sample are quartz, chlorite, and biotite. Copper and manganese are leachable from the ...

Metal cations have great effects on the flotation of silicate minerals whereas the interaction mechanism is unclear. Single mineral flotation demonstrated that the recovery of biotite rose to 94.69% and 96.41%, and that of quartz declined to 1.21% and 2.01% after introducing small amounts of Ca 2+ and Mg 2+, respectively.Artificial mixed mineral tests …

Keywords: synthetic muscovite; biotite; oxidation; coal tailing; crystal structure 1. Introduction Biotite and muscovite are two phyllosilicate minerals within the mica family that are commonly found in igneous and metamorphic rocks. Biotite has a small number of commercial uses, while muscovite has the greatest commercial value due to its special
The probability of failure of tailing dams and associated risks demand improvements in engineering practice. The critical state line provides a robust framework for the characterization of mine tailings. New experimental data for nonplastic platinum tailings and a large database for tailings and nonplastic soils (grain size between 2 and 500 μm) show that …
The samples do not represent the whole mining tailings area of their origin, but only the shallow tailings at one sampling point. Surface of the tailing dumpling may differ from the overall composition of the tailing deposit. ... FMT1 contained 6% biotite, which is a Fe-rich mineral, which could partly explain the presence of Fe in the mullite ...
