Analyzing the rheological behavior of medium fine iron ore slurry.

A slurry pipeline is a specially designed pipeline used to transport the tailings, wastes from the mining, ores like iron or coal to long distances. A commercially tested solution for the transport of iron ore slurry over the farthest distances in a pipeline includes various parametric checks. For the slurry to move without any hassle in the pipe maintaining the required velocity, it is important to keep some parameters in the desired limits, the most important of which is the rheological characteristics of the slurry. The rheological characteristics gives us an idea about the viscous properties, stress strain behavior of the iron ore exhibiting in its surrounding. The rheological parameters of the iron ore slurry were measured using a high precision Anton paar RheoloabQC Rheometer. At different concentrations the samples were tested keeping the particle size to be same for all the observations. While the method has been kept the same for the experiments, different rotating tools are used in the rheometer to check the accuracy of the data as well as to draw a comparison on the data obtained from them for each level of concentration. Our study majorly deals with a comparative assessment of the performance of the various rotating tools to study the rheology of the iron ore slurry.
