Gold tailing unfired ceramsite and preparation method thereof
The invention belongs to the technical field of ceramsite preparation, and particularly relates to gold tailing unfired ceramsite and a preparation method thereof. The preparation method comprises the following steps: mixing gold tailings and industrial waste residues, and grinding to obtain powder; uniformly mixing an alkali activator, a foaming material and water to obtain a mixed solution; adding the powder and the mixed solution into a disc type granulator for granulation to obtain ceramsite before maintenance; covering the surface of the ceramsite before curing with a layer of film, naturally curing at room temperature for 12-48 hours, and then performing mineralization curing in the presence of carbon dioxide for 3-7 days to obtain the ceramsite. The preparation method can be carried out at normal temperature and normal pressure, the obtained gold tailing unfired ceramsite has the advantages of high carbon sequestration and low energy consumption, and co-treatment of comprehensive utilization of gold tailings and sealing and utilization of carbon dioxide is realized.
本发明属于陶粒制备技术领域，具体涉及一种黄金尾矿免烧陶粒及其制备方法。该制备方法包括以下步骤：将黄金尾矿与工业废渣混合后研磨，得到粉料；将碱激发剂、发泡材料与水混合均匀，得到混合液；将所述粉料和混合液加入圆盘式造粒机进行造粒，得到养护前陶粒；在所述养护前陶粒表面覆盖一层膜，在室温下自然养护12～48h，然后在在二氧化碳存在下进行矿化养护3～7d，即得。该制备方法在常温常压下即可进行，所得黄金尾矿免烧陶粒具有固碳高、能耗低的优点，实现了黄金尾矿综合利用与二氧化碳封存利用的协同处置。
