Abstract null null Due to the significant effect of abnormal arrivals on localization accuracy, a novel acoustic emission (AE) source localization method using clustering detection to eliminate abnormal arrivals is proposed in the paper. Firstly, iterative weight estimation is utilized to obtain accurate equation residuals. Secondly, according to the distribution of equation residuals, clustering detection is used to identify and exclude abnormal arrivals. Thirdly, the AE source coordinate is re...

Abstract null null The flotation of diasporic bauxite is to separate diaspore (valuable mineral) from aluminosilicate minerals (gangue minerals, mainly including kaolinite, illite and pyrophyllite), and the microscopic interaction force between the two types of minerals and air bubbles determines the separation efficiency. In this paper, based on the extended Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, the van der Waals, electrostatic and hydrophobic interaction between particles of the four...

Abstract null null The direct sulfidization of cuprite is inefficient because cuprite is a copper-oxide mineral with a strong surface hydrophilicity. In this study, oxidant was used to modify cuprite surfaces to regulate the sulfidization of cuprite. Microflotation tests showed that the flotation recovery of pre-oxidized cuprite was nearly 25% higher than that of direct sulfidization flotation, which indicates that the cuprite surface activity was enhanced after pre-oxidation by Cu(I) species (w...

Abstract null null Sandstone is widely distributed in cold regions and the freeze–thaw deterioration of them has caused many geological engineering disasters. As an important and direct index of frost resistance, the strength loss of sandstones under freeze–thaw actions should be investigated to provide a guidance for the stability assessment of geological engineering. In this research, the UCS (Uniaxial compressive strength) loss of six typical sandstones with different water contents after 0, ...

Abstract null null To achieve the utilization of the abandoned ultrafine ilmenite (−20 μm) produced in the titanium magnetite processing plant in Panzhihua, the superconducting high-gradient magnetic separation (SMS) technology was proposed in this study. After optimizing the conditions of magnetic intensity, feeding and pulsation, an SMS concentrate with TiO2 grade of 16.03% and TiO2 recovery of 66.39% was obtained through one roughing–one cleaning pre-concentration flowsheet. The specific magn...

Abstract null null In this investigation, a chelating agent of amino trimethylene phosphonic acid (ATMP) was introduced to eliminate the adverse effect of seawater in molybdenite flotation. Microflotation results presented that high flotation recovery of molybdenite was achieved in freshwater using kerosene as the collector, but it was significantly decreased in the presence of seawater when pH > 9.5. Among the main ions in seawater, magnesium and calcium ions played a more detrimental role than...

Abstract null null Ultra-thick steep coal seam mining will inevitably lead to the increase of greater and violent ground subsidence and deformation. A subsidence control method by inversely-inclined slicing and upward mining is proposed in this paper. By this method, the sequence of collapse of overlying strata and the direction of propagation of strata movement are changed, the extent of roof-side deformation thereby is lessened, and boundary angle of roof-side subsidence is reduced by 5°–10°. ...

Abstract null null The differential evolution (DE) algorithm was deployed to calibrate microparameters of the DEM cohesive granular material. 4 macroparameters, namely, uniaxial compressive strength, direct tensile strength, Young’s modulus and Poisson’s ratio, can be calibrated to high accuracy. The best calibration accuracy could reach the sum of relative errors REsum

Abstract null null Dynamic disasters, such as rock burst due to the breaking of large area stiff roof strata, are known to occur in the hard rock strata of coal mines. In this paper, mechanical models of the fracturing processes of thick hard rock strata were established based on the thick plate theory and numerical simulations. The results demonstrated that, based on the fracture characteristics of the thick hard rock strata, four fracture models could be analyzed in detail, and the correspondi...

Abstract null null A novel porous nanocomposite, cross-linked chitosan and polyethylene glycol (PEG) bead-supported MnFe2O4 nanoparticles (CPM), was developed as an efficient adsorbent to remove metalloid (As(III)) and heavy metals (Cd(II), Cu(II), and Pb(II)). The characteristics of CPM showed a porous structure, well dispersed MnFe2O4, and several of hydroxyl and amino groups ( OH, null NH2). Batch experiments demonstrated that the best adsorption property of As(III), Cd(II), Cu(II), and Pb(II...
