The comprehensive utilization of tailings is one important topic for the sustainable development mining industry in China. paper does experiment laboratory by way magnetic separation to reclaim iron mineral from a certain concentrating mill molybdenum minerals. Finally, result this indicates that through open process rough and fine at first---grinding finely once again tailings, we can get concentrate with yield 0.39%, grade 63.27% recovery 10.57%.
It is a consensus that salt heaving and frost are urgent typical distress in the sulfate saline soil area. To further investigate microscopic performance of pavement structure this special area, Jinan-Dongying Freeway Shandong Province selected as case study engineering mechanic responses under heaving, traffic loads were analyzed through finite element (FE) Program (ANSYS). In paper, process was divided into 3 stages FE models established based on fluid–structure interaction (FSI) model....
Landslides on gently inclined loess–bedrock contact surfaces are common geological hazards in the northwestern Loess Plateau region of China and pose a serious threat to lives property local residents as well sustainable regional development. Taking Libi landslide Shanxi Province case study (with dimensions 400 m × 340 m, maximum thickness 35.0 volume approximately 3.79 104 m3, where slip zone is located within highly weathered sandy mudstone layer Upper Shihezi Formation Permian System),...
Two-dimensional finite element model of Longmenshan area was built on the basis depth study geological structure conditions and rock mechanical properties in area, tectonic stress field variation process fault belt were inversed after earthquake. The results show that: (1)After earthquake, maximum principal appears endpoint, partial inflection point, intersection Xianshuihe Minjiang fault, Animaqing-lueyang Fault. is overall NEE to SEE.(2)After shear distribution more uniform, compared...
This paper investigates the transient flow field characteristics and rock cuttings trajectory during large-diameter reaming drilling, aiming to address issue of low debris removal efficiency. By establishing a liquid-solid two-phase numerical model, bundled down-the-hole hammer for 830mm drilling was simulated, velocity, pressure distribution, movement within hole bottom return channel were analyzed. The study found that bit rotation significantly influences field, increasing area high-speed...
A non-in situ measurement method for gas hydrate thermal conductivity was established, including the sample preparation, transfer, loading, and measurement. Taking tetrahydrofuran (THF) methane as examples, detailed process investigated by many experiments. THF samples were prepared combined of aqueous solution + temperature oscillation aging, while compacted ice powder supplementary aging. The box, quick-opening reactor, mold developed to improve quality, shorten preparation time, reduce...
This paper adopts sedimentation experiment to study the process of one molybdenum ore flotation tailings and investigate effects lime sodium silicate on performance tailings. Through speed compressive layer density, it reveals rules these Meanwhile, explores dry beach The research shows that: could effectively ameliorate non-easy caused by silicate; when dosage is 300～800g/t, can reach best reasonable pH value 9-10. Besides, also indicates that both are unfavorable form concentrating mill.
In the process of natural gas transportation in pipeline, because contains mud and sand, pipeline will undergo erosion wear under impact gas-solid two-phase flow. Erosion seriously reduces performance inner wall which is not conducive to stability conveying safe operation equipment. Among them, special pipe fittings such as tee bend are especially serious. this paper, T-shaped simulated by FLUENT software, fluid-solid coupling analysis completed. The characteristics flow different fluid...
