摘要
The present invention relates to a method for determining the clay content of an oil sands tailings stream. The method comprises treating an oil sands tailings stream with a PEO flocculant, passing the mixture through a dynamic mixer comprising a mixer shaft and a power drive for rotating said shaft, wherein the power input needed to maintain a mixer rotational speed (RPM) is measured. For an oil sands tailings stream having a specified solids content, the power measurement and PEO dosage level is correlated to a clay content characterization index, for example methylene blue index (MB I), to determine in real-time the clay content during the processing of an oil sands tailings stream.
