Method for preparing closed-cell ceramsite from iron ore tailings
The invention relates to a method for preparing closed-pore ceramsite by using iron ore tailings, and provides the following solution measures: taking the iron ore tailings as a main raw material, adjusting the contents of SiO2 and Al2O3 in the material through quartz powder and potassium feldspar, introducing SiC as a foaming agent, and firing at high temperature to obtain light ceramsite dominated by closed pores, on the basis of keeping light weight and heat preservation and heat insulation of the light ceramsite, an advanced infiltration process in a process of preparing concrete by using the light ceramsite as light aggregate is reduced, the process flow is simplified, and the production efficiency is improved; meanwhile, the special requirements of the water treatment process are met by utilizing the closed hole characteristic.
本发明涉及一种利用铁矿尾矿制备闭孔陶粒的方法，提出如下解决措施：以铁矿尾矿为主要原料，通过石英粉和钾长石调整物料中SiO2和A12O3含量，引入SiC作为发泡剂，在高温下烧成获得以闭气孔为主导的轻质陶粒，希望在保持轻质陶粒质轻、保温隔热的基础上，减少在作为轻质骨料制备混凝土工艺时的提前浸渗工艺，简化工艺流程，提高生产效率；同时利用闭孔特点，满足水处理过程的特殊需要。
