Abstract:
Tailings are a rest product from the extraction of metals and minerals, and is therefore produced in large volumes by all mining companies. One common way to store tailings material is to deposit it as a hydraulic slurry on a tailings impoundment, where the tailings are held in place by tailings dams. Deposit and discharge of tailings, often conducted along the dams, causes a particle segregation which creates different fines contents (percentage of particles smaller than 0,063 mm in the tailings) in the impoundment at various distances from the discharge.

Abstract Permeability plays a key role in liquid composite molding processes for mold and process design.

The racetracking effects, the permeability of the high permeability layer used in vacuum assisted RTM and the equivalent permeability in the channels used in SCRIMP were also investigated in this stud

Abstract:
Abstract Hydrogen is poised to become one of the most promising alternative clean sources of energy for climate change mitigation. The development of a sustainable hydrogen economy depends on the global implementation of safe and economically feasible intersessional hydrogen storage and recovery. However, the current body of literature lacks comprehensive numerical characterization of the multiphase flow of hydrogen-brine and how geological parameters at the pore scale influence the multiphase flow. This study presents a pore network simulation of hydrogen-brine and cushion gas-brine relative

Abstract:
Abstract A good understanding of woven fiber preform permeabilities is critical in the design and optimization of the composite molding processes, yet these issues remain unresolved in the literature. Many have attempted to address permeability predictions for flat undeformed fiber preform, but few have investigated permeability variations for complex three-dimensional molds. In this study, the objectives are to: (i) first provide a brief review of existing methods for the prediction of the fiber mat permeability; (ii) postulate a more realistic representation of a unit cell to account for suc

Abstract:
Permeability values for a range of fine-grained deep-sea sediments are presented and evaluated in terms of index properties such as plasticity, grain size and carbonate content. It is found that whereas clay-rich sediments have similar permeabilities to those of equivalent land-based fine-grained soils, the presence of volcanic, carbonate and other non-clay fractions tends to increase permeability somewhat. Volcanic silty-clayey soils from Hawaii have comparable permeability values, although they can be slightly more permeable.

Abstract:
This is the first regional porosity/permeability study to incorporate petroleum industry laboratory core analyses submitted to the Ontario government and managed by Ontario's Oil Gas and Salt Resources Library. This study comprises 11,759 analyses for the Early Silurian Lockport Group of southwestern Ontario from 150 drill cores. The Lockport Group consists of a cyclic succession of dolostones and minor limestones comprising, in ascending order: Gasport, Goat Island, Eramosa, and Guelph formations. This stacked carbonate succession was deposited on an eastward-deepening carbonate ramp, extendi
