with crushing granularity. The fitting formulae of rebound distance for coal and gangue were obtained with experimental data. The correlation coefficient R2 of the fitting formula for coal is 0.835 while... of coal and gangue with different granularity ranges 图7 不同冲击速度范围内矸石和被破碎煤的反弹距离比较 Fig. 7 Rebound distance comparison between gangue and crushed coal with different impact velocity ranges 表3 ......
extraction was achieved with appropriate control of ore granularity. Key words: bacteria; particle size; column-leaching; nickel; bioleaching Cite this article as: WANG Xin, YANG Hong-ying, ZHANG Qin... by the small particles. As long as ore with appropriate granularity is used, this outcome can be avoided. The results of this particle size experimental investigation should provide useful reference data......
) analysis, UV-Visible absorption spectroscopy and thermal analysis (DSC) techniques. The results show that mean granularity of the almost spheric Ag nanoparticles are 15 nm and 80 nm in 100% He and 100% Ar......
carbide powder with Fisher sub-sieve sizer granularity of 8.06 μm and cobaltous nitrate hexahydrate were used as the starting materials, and the triethanolamine (TEA) was used as the reducer. The phase......
on granularity and morphology of the as-prepared stainless steel powders were discussed. The results show that the finer stainless steel powders with higher sphericity are produced by the gas and solid dual......
of the product were investigated through XRD and SEM. The results show that the powder is spherical in the phase of TiO2-Ag2SO4. The granularity of the particles increases from 10.7nm to 28.7nm......
particles in the same mine. The results show that the impact crushing probability of gangue particles whose granularity is between 50 mm and 100 mm has linear relation to the impact velocity......
was granularity minus 0.30 mm powder and rich in specularite, limonite and Mg-Mn siderite from Jiuquan Iron & Steel (Group) Co. Ltd (JISC) were briefly reviewed. The phase transformation and microstructure......
: granularity of pre-grinding 74.95% (particle parameter is less than 0.038 mm), dosage of lime 19.35%, reduction temperature 1 400 ℃, reduction time 60 min. The best results are T(Fe)71.01%, ε(Fe) 99.5......
