J. Cent. South Univ. (2019) 26: 43-62 DOI: https://doi.org/10.1007/s11771-019-3981-2 Data driven particle size estimation of hematite grinding process using stochastic configuration network... of Springer Nature 2019 Abstract: As a production quality index of hematite grinding process, particle size (PS) is hard to be measured in real time. To achieve the PS estimation, this paper proposes......
J. Cent. South Univ. (2021) 28: 648-656 DOI: https://doi.org/10.1007/s11771-021-4634-9 Influence of B4C particle size on microstructure and damping capacities of (B4C+Ti)/Mg composites YAO Yan-tao... GmbH Germany, part of Springer Nature 2021 Abstract: To study the influence of B4C particle size on the microstructure and damping capacities of (B4C+Ti)/Mg composites, in situ reactive infiltration......
Electrochemical studies on interplay of mineralogical variation and particle size on bioleaching low grade complex sulphide ores P. A. OLUBAMBI1, J. H. POTGIETER2, S. NDLOVU3, J. O... at a particle size of 75 μm, while electrochemical investigations reveal the highest dissolution at particle size of 106 μm. Electrochemical results show that sphalerite rich phase has the highest dissolution......
environment for the formation of small size bubble due to hydrodynamic cavitations, and these fine bubbles have high probability of bubble-particle collision, which will enhance fine particle... air bubble in flotation cell than those created by normal conditioning. Key words: fine particle flotation; high intensity conditioning; particle aggregation; bubble size measurement
synthesis, nanocrystalline particle 1 Introduction In recent years, nanocrystalline materials with size-dependent optical, electronic and magnetic properties, due to the reduction of grain size..., the particle size and the specific surface area can be controlled by simply modifying the acidity/alkalinity of the precursor solution, and the study on the essential of this influential factor is in progress......

depends on both size and shape conditions, among which the temperature suppression is strongly influenced by the particle size and the shape effect is comparably minor. The calculation values... on its shape factor and atomic number. Here the atomic number can be regarded as one index of particle size, as it is natural that more atoms lead to larger size of nanoparticles. The values of shape......

with the apparent activation energy of 80.175 kJ/mol. Moreover, the oxidation rate is closely related to particle size of the concentrate. The smaller the particle size is, the larger the oxidation rate is. Key words: molybdenite; oxidation; roasting; kinetics; particle size 1 Introduction Molybdenum is widely used in materials and chemical industry [1,2]. Molybdenite is the main mineral of molybdenum......
