Tailing recycling and harmless treatment method
The invention discloses a tailing recycling and harmless treatment method, and the method comprises the following steps: putting tailings, a sodium-containing alkaline compound and a water medium intoa sealed reaction kettle for hydrothermal reaction, performing solid-liquid separation on the hydrothermal reaction product, concentrating the obtained liquid phase to obtain a sodium silicate product, and performing high-temperature treatment on the obtained solid phase to stabilize heavy metals. The method not only realizes efficient recovery of silicon resources in the tailings, but also realizes stabilization treatment of heavy metals in the tailings, and can be popularized and applied on a large scale.
本发明公开了一种尾矿资源化及无害化处理方法，该方法是将尾矿与含钠碱性化合物及水介质置于密封反应釜内进行水热反应，水热反应产物通过固液分离，所得液相进行浓缩得到硅酸钠产物，所得固相经过高温处理，实现重金属稳定化，该方法不但实现了尾矿中硅资源的高效回收，而且实现了尾矿中重金属的稳定化处理，可以大规模推广应用。
