Diatomite Experimental Study on New Wet Purification Process

Wet centrifugal separation process is used to purify diatomite by analyzing the properties of diatomite raw ore in Linjiang city, Jilin province. Experimental results determine the affecting sorting important indicators, including scrubbing agent and dosage, sieving mesh, centrifugal separation. The concentration of SiO2 in the final diatomite is 86.76%, reaching primary soil standard. Compared with gravity sedimentation purification process, new technology method saves much time and achieves the ideal separation effect.
