Test on Flocculation and Sedimentation Characteristics of Phosphorus Tailings Based on Intelligent Test Device
In order to improve the intelligence level and analysis accuracy of flocculation sedimenta-tion test,the flocculation sedimentation characteristics test of phosphorus tailings was carried out by the self-developed tailings intelligent thickening test device.The results show that the relationship between the feed concentration of tail mortar and the solid flux is an inverted hook function,and the solid flux is main-tained at a high level when the feed concentration is 10%～18%.With the increase of the feed concentration of the tailings slurry,the underflow concentration and the turbidity of the overflow water increase.The opti-mal feed concentration of the tailings slurry is 15%,and the underflow concentration exceeds 72.7%.The automatic operation and intelligent analysis of the tailings intelligent thickening test device improve the ac-curacy of the test results,which can provide a reference for the mine to select the appropriate flocculation sedimentation parameters.
