摘要：In order to treat tailings more economically and effectively and improve the pumping efficiency of the slurry, the pumpability of full tailings consolidation and discharging slurry (FTCDS) was tested. The three evaluation indicators, i.e., slump, slump flow, and bleeding rate, were measured under the conditions of HA-7 and PO42.5 as the cementing material, with the slurry concentration of 75% to 80% and the cementing material dosage of 2% and 3%. Based on these three evaluation indicators, the pumpability of the FTCDS was analyzed and evaluated, and the slurry ratio suitable for pumping was obtained. The results show that the slurry can be pumped well when HA-7 selected as the new cementing material, the concentration is 75% to 79%, and the amount of cementing material is 2%. The research results have implications for similar processes.
