Abstract [en]

Design of mine-tailing pipelines and other short-distance applications involves many of the considerations of long-distance pipeline transportation and is often complicated by variation in particle sizes and solid throughput. In this study, a modified tube viscosimeter is used to obtain rheological data for clay, coal, and iron ore slurries. Temperature-dependent changes in the rheological properties are evaluated for some applications in cold regions. A modified tube viscosimeter was constructed in order to eliminate some correction problems with this type of equipment. Rheological data for clay, coal, and iron ore slurries were obtained with both tube and rotational viscosimeters, which means that a large span of shear rates was investigated. Temperature-dependent changes in rheological properties were evaluated for some applications in cold regions. Freezing is an effective means of thickening fine-particled slurries such as clay-water mixtures and sludges. The rheological results with kaolin and coal slurries showed that the flow properties at constant solids concentration were not changed after a freeze-thaw cycle
