Batch gravitational sedimentation of slurries.
We investigated the batch settling behavior of the kaolin slurry and the UK ball clay slurry at various initial solids fractions (phi(0)s) using a computerized axial tomography scanner (CATSCAN). The spatio-temporal evolutions of solids fractions in the consolidating sediments were continuously monitored. Since the interface between the sediment and the supernatant of the investigated slurries ...
متن کاملThe Effect of Colloidal Forces on the Sedimentation and Reslurrying Characteristics of Silica Slurries
Preliminary work has been completed to investigate the effect of particle-particle interaction forces on the flow properties of silica slurries. Classically Hydrotransport studies have focused on the flow of coarse granular material in Newtonian fluids. However, with current economical and environmental pressures, the need to increase solid loadings in pipe flow has lead to studies that examine...
متن کاملFully-continuous Supercritical Fluid Extraction of Naphthalene from Soil Slurries
The research objective was to build a fully-continuous lab-scale supercritical fluid extraction process to remove naphthalene from soil slurries. Both the carbon dioxide and the soil slurry were pumped into an extraction vessel simultaneously and continuously for the duration of an experimental run. Delhi Loamy Sand spiked with approximately 10 000 ppm (wt) of naphthalene and water comprised th...
متن کاملSimple mass balance controllers for continuous sedimentation
The rational use of water in the mineral processing industry has become an im-portant issue due to the geographical location of many plants. The increase of capacity in manycopper concentrators has lead to an increased effort for recovering the maximum amount ofwater in the solid-liquid separation process. Thickeners work continuously to produce a con-centrated underflow and a w...
متن کاملDynamic and Steady-State Behavior of Continuous Sedimentation
Continuous sedimentation of solid particles in a liquid takes place in a clarifierthickener unit, which has one feed inlet and two outlets. The process can be modeled by a nonlinear scalar conservation law with point source and discontinuous flux function. This paper presents existence and uniqueness results in the case of varying cross-sectional area and a complete classification of the steady...
