P, KALALA J T. Investigation of particles with high crack density produced by HPGR and its effect on the redistribution of the particle size fraction in heaps[J]. Minerals Engineering, 2013, s43/44(4..., Canada, 2007: SCA2007-17. [39] KNACKSTEDT M, ARNS C, LIMAYE A, SAKELLARIOU A, SENDEN T, SHEPPARD A, SOK R, PINCZEWSKI W V, BUNN G. Digital core laboratory: Properties of reservoir core derived from 3D......
affect the formation of mineral deposit, such as the pore-fluid flow channel, temperature distribution, pore pressure variation and physical chemical properties of surrounding rocks [10-12], it is hard... and the temperature gradient is the driving force of pore-fluid flow. The metallogenic temperature of chalcopyrite in the Kaerqueka polymetallic deposit is between 250 and 350 °C. The corresponding......
to liquid (L/S), absorption temperature, the inlet SO2 concentration, the O2 concentration and SO42– on desulfurization efficiency were researched. The chemical and physical properties of raw and spent.... Effects of the ratio of liquid to solid (L/S), the absorption temperature, the inlet SO2 concentration, the O2 concentration, SO42- and other different components of Bayer red mud on desulfurization......
(11): 3218-3224. HAN Xin-gang, XI Xiao-li, MA Li-wen, NIE Zuo-ren, ZHOU Zhi-li. Separation properties of ion to cobalt and nickel in complexation-precipitation system[J]. The Chinese Journal... were studied, respectively. The precipitation rates of Cu2+, Co2+, Zn2+, and Mn2+ were as high as 99%. The precipitates, CuS, Co(C2H5OCSS)2, ZnS and MnSO4, can be reused as raw materials in metallurgy......
history, the initial temperature gradient is changed, so that a new gradient of temperature is formed within the UCE. Since the temperature in the lower part of the upper crust is higher than... and the roughness of the flow channels, which are usually generated by connected pores in the porous medium. Because the upward buoyant force is proportional to the pore-fluid temperature, there exists......
, sensitivity analysis of the influencing factors which affect the temperature increment at the thermal boundary was implemented using the method of grey relation. Finally, considering the influences of all factors and their interaction, the quadratic regression orthogonality analysis method was used to study the temperature increment at the thermal boundary. A prediction model on thermal boundary condition......
the properties of large- volume, diversity and high-velocity. Consequently, under the background of mechanical big data, how to rapidly draw the effective characteristics becomes a key research issue... of 15 trials obtained by the proposed method are in the range of 97.73%-99.73%. In addition, the average defect diagnosis accuracy is 99.01%. Therefore, the diagnosis accuracy is relatively high......
concentration of germanium, and the experimental results such as the extraction efficiency are required. Table 2 illustrates the initial conditions of experiments at room temperature used for modeling. Table 2 Initial conditions of LLX system at room temperature used for modeling The solver method tried to find a Kex value by which the sum of squares function was minimized. In each step......
of these members was set to be aluminum alloy AA6060-T4 due to having greater strength to weight ratio compared with other materials like steels. AA6060-T4 has the following mechanical properties: yield stress..., and the mechanical properties of which were listed in Section 2. The procedure of performing the experiments was such that the tubes were fixed on the lower support and the upper support was moved......
/average effect on the distribution/transformation behaviors of HMs. After liquefaction of SS in pure water, the contamination degree of HMs is mitigated from high level (25.8 (contamination factor... of attention [5, 7]. Considering that SS usually has high content of water (75%-80%, after mechanical dehydration) [8, 9], water is the most widely used solvent in the liquefaction of SS [10-15......
