Method for preparing ultralight ceramsite from molybdenum tailings, iron tailings and waste glass powder
The invention relates to a method for preparing ultralight ceramsite by utilizing molybdenum tailings, iron tailings and waste glass powder, the ultralight ceramsite is prepared from the following raw materials in parts by mass: 40-70 parts of molybdenum tailings, 10-40 parts of iron tailings and 5-20 parts of waste glass powder, and 0.3-0.5 wt.% of SiC is added on the basis of the total weight of the molybdenum tailings, the iron tailings and the waste glass powder; the molybdenum tailings, the iron tailings and the waste glass powder are subjected to ball milling and sieving and then are uniformly mixed with SiC, water is added for granulation, drying and sintering are performed, the ultra-light ceramsite is obtained, the density of the ultra-light ceramsite is smaller than 500 kg/m < 3 >, and the water absorption rate is lower than 4%. The ultra-light ceramsite is prepared through collaborative sintering of mineral composition characteristics and chemical composition differences of the molybdenum tailings, the iron tailings and the waste glass powder, effective utilization of waste resources such as the molybdenum tailings, the iron tailings and the waste glass powder can be achieved, and the ultra-light ceramsite with the density lower than 500 kg/m < 3 > and the water absorption lower than 4% is obtained.
本发明为利用钼尾矿、铁尾矿和废玻璃粉制备超轻陶粒的方法，所述的超轻陶粒由以下质量百分比的原料制备而成，钼尾矿40‑70份、铁尾矿10‑40份，废玻璃粉5‑20份，以钼尾矿、铁尾矿和废玻璃粉的总重量为基准，还添加0.3‑0.5wt.％SiC；所述钼尾矿、铁尾矿和废玻璃粉球磨、过筛后与SiC一起混合均匀后进行加水造粒，烘干后进行烧结，获得超轻陶粒，所述超轻陶粒的密度小于500kg/m3，吸水率低于4％。利用钼尾矿、铁尾矿和废玻璃粉的矿物组成特点和化学组成差异协同烧结制备超轻陶粒，可实现钼尾矿、铁尾矿和废玻璃粉等废弃资源的有效利用，并获得密度低于500kg/m3，同时吸水率低于4％的超轻陶粒。
