| Abstract: | The properties of middle grade phosphate ores in Qingshuigou area is complicated.After it is ground to -0.147mm 92.8%,the friction makes it charged by the integrated action of the vibration and airflow.Then the electrostatic separation flow sheet of one-stage roughing,one-stage concentrating,and one-stage scavenging with suspension electrostatic separator is adopted.The resultes of electrostatic separation are:the content of P 2O 5 clean ore is up to 30.23% while it's P 2O 5 of raw ore is only to 24.47%,and the recovery of clean ore is up to 83.26%,and the content of impurity of it is up to standard. |
