Tailing pond selling method
The invention belongs to the technical field of tailing pond treatment, and discloses a tailing pond selling method. The method comprises the following steps of step 1, preparing a filling material byutilizing mining waste rocks and mining tailings in a grading manner; step 2, dewatering the graded filling material; step 3, conducting slurry treatment of the graded filling material; step 4, filling. According to the method, replacement between waste rock mining and the tailing pond mining tailings is formed, specifically, the mining waste rocks are made into sandstone aggregates, and the mining tailings are used for filling a goaf formed by waste rock mining, so that benefit maximization of tailing pond selling treatment is achieved. Specifically, the mining tailings of the tailing pond are subjected to grading treatment, and coarse particle tailings are used as the sandstone aggregates to be sold after pollutants are deeply removed or innocent treatment is conducted. Oversize fine particle tailings are mixed with sandstone waste, and the goaf formed by mining the waste rocks is filled. Undersize fine particle tailings adjust the concentration of filling slurry, and can also be used as a preparation raw material of a novel cementing agent.
本发明属于尾矿库处理技术领域，公开了一种尾矿库销库的方法，包括步骤1：利用开采废石和回采尾砂分级式制备充填料；步骤2：分级式充填料脱水；步骤3：分级式充填料的浆料处理；步骤4：充填；在本发明中，形成废石开采与尾矿库回采尾砂之间的置换，具体表现开采废石制成砂石骨料，并利用回采尾砂充填废石开采所形成的空区，以实现尾矿库销库处理的利益最大化；具体对尾矿库的回采尾砂进行分级处理，其中：粗颗粒尾砂在深度去除污染物或无害化处理后作为砂石骨料进行售卖；筛上细颗粒尾砂与砂石废料混合，对开采废石所形成的空区进行充填；筛下细颗粒尾砂对充填浆料浓度进行调整，并且还可用做新型胶结剂的制备原料。
