20th International Seminar on Paste and Thickened Tailings

Dr. Behnam Pirouz, Manager of our Slurry Transport Services, from our Melbourne office attended and presented a technical paper at the 20th International Seminar on Paste and Thickened Tailings. The seminar was held in Beijing- China from 16 to 18 June, 2017.

The paper was entitled “Variability of Thickeners Underflow Solids Concentration and Flowrate” and was co-authored by Dr. Sadegh Javadi and Keith Seddon.

The operational fluctuations of tailings thickeners have the potential to cause significant impacts on the tailings transport system and the tailings deposition at a Tailings Storage Facility (TSF).

The statistical analysis of actual recorded data of underflow solids concentration and flowrate of different thickeners is presented in this paper. The collected data has been gathered from the operation of four different mines; one Zinc- lead, two Copper and one Gold mine.

The variability in these two important parameters can be related to process fluctuations, design or construction defects including instrumentation and controls, the variability in mine ore body during the life of the project or operation of the thickener.

The analysis shows that the actual performance of the thickener can be significantly different from what is usually considered at a design stage.
