Effective monitoring and control of a mineral flotation process necessitates accurate and rapid on-line analysis of the slurry flows. Recent development of lightweight and low-cost visible and near-infrared (VNIR) imaging spectrographs has provided new interesting possibilities also in mineral froth and slurry analysis. The intelligent combination of VNIR reflectance spectroscopy with the tradi...

This work aimed to contribute to the modelling of slurry flows in horizontal pipes supported by experimental data gathered in a well instruments pilot rig. An ultrasonic sensor system was inserted in the pipe in order to calculate the slurry velocity profiles using a time domain correlation method. Effects of particles concentrations and slurry flow rates were investigated. A comparison of the ...

the design of cement slurry for horizontal wellbores is challenging as it must present very high quality cement slurry properties e.g. zero free water, less than 50 cc api fluid loss value, appropriate rheology and yield point for effective displacement, adequate compressive strength, which is critical for lightweight slurries, and finally stable cement column behind casing. the main objective ...

Prediction of the apparent viscosity of a slurry suspended fine particles is important for developing slurrytreating processes. After Einstein’s formulation for the apparent viscosity of a dilute, completely dispersed slurry, several viscosity equations were proposed. However, viscosity depends not only on the volume fraction of solid particles but also on many factors such as particle shape, p...

ORAL PRESENTATIONS coli levels, suggesting that alternative methods of slurry application may be considered in MRDT104 infected swineherds, regardless of infection level. The different pattern of decay for slurry injection is due to a sampling error on day 0. Linear extrapolation suggests that the actual E. coli counts on this plot on day 0 probably were at least log 3.5 cfu/g. This study also ...
