Method for preparing foamed ceramic by using iron tailings synergistic metallurgical solid waste
The invention provides a method for preparing foamed ceramic by utilizing iron tailings and metallurgical solid wastes, and belongs to the technical field of comprehensive utilization of tailings. The method comprises the following steps: firstly, grinding and screening iron tailings, ferrochrome slag, manganese smelting slag, fly ash, kaolin and a foaming agent, adding water for wet grinding, then granulating, filling a blank into a mold, pressing, sintering at high temperature, and after sintering is completed, cooling along with a furnace to obtain the foamed ceramic. The invention has the advantages of high solid waste utilization rate, light weight, high strength and good heat insulation effect.
本发明提供一种利用铁尾矿协同冶金固废制备发泡陶瓷的方法，属于尾矿综合利用技术领域。该方法首先将铁尾矿、铬铁渣、锰冶炼渣、粉煤灰、高岭土和发泡剂研磨筛分后，加水湿磨，然后造粒，将坯料装模与压制后，进行高温烧结，烧结完成后，随炉冷却得到发泡陶瓷。本发明固废利用率高，制品轻质，强度高，保温隔热效果好。
