Particle shape and size are main factors influencing particle breakage. Single‐particle breakage tests were conducted on irregular magnetite ore using modified drop weight impact equipment to analyze the effect of specific energy. A method measure effective energy is presented. Ore particles with different sphericities sizes broken into several fragments differing energies in tests. Experimental studies indicate that significantly influences loading mode progress; has an obvious relationship...
In this study, we developed a pipeline transport model to investigate the influence of particle sedimentation factors on slurry transportation through pipelines. The tracking module software was used simulate process, and influences rate were analyzed considering concentration, size, flow velocity. established exhibited small calculation errors. addition, results revealed that proposed is reliable for calculating degree various sedimentation. effect explored positively related size adversely...
In order to study the strength characteristics and hydration mechanism of cemented ultra-fine tailings backfill (CUTB), uniaxial compressive (UCS) tests CUTB classified (CCTB) with cement-tailing ratio (C/T ratio) 1:4 1:6 curing ages 3, 7, 14 28 days were carried out. The products morphology paste (CPB) analyzed by X-ray diffraction (XRD) scanning electron microscope (SEM). results show that UCS is significant compared CCTB under same conditions; greater C/T age, difference value. growth...
The permeability characteristics of iron tailings are one the important factors affecting stability dam. properties undisturbed and disturbed were analyzed from various aspects such as FC value, gradation, particle size, specific surface area, interparticle void ratio with water head test in laboratory. results show that coefficients affected by fine particles content ( ). threshold is about 40%. traditional formulas for calculating coefficient applied. But inaccurate. relationship between...
The stability of iron tailings dam is affected by the permeability tailings. Considering influence it, it necessary to analyze so as prevent recurrence Brazilian accidents. Nevertheless, results from some prediction equations (Terzaghi equation, Hazen and Kozeny equation) cannot be accurate. Iron are various they can divided into three categories: (1) silt content less than 40%; (2) more 40%, while clay 15%; (3) 15% 30%. Correspondingly, proposed calculate disturbed undisturbed for types....
