The invention discloses a preparation method of magnetic ceramsite with high adsorption performance. A composite solution was prepared with FeCl 3 and K 2 CO 3 as raw materials as activators, and then the sludge, iron tailings, construction slag and sawdust were mixed and stirred to obtain a mixture, and the mixture was immersed in the composite solution for activation for 8~ After 12 hours, the impregnated and activated mixture is aged for 8 to 12 hours, and then rolled for another 30 to 40 minutes. , cooled and sieved to obtain ceramsite. The ceramsite prepared by the invention has the characteristics of light weight, high strength, low thermal conductivity, magnetic properties and the like. |
