Tailing solid waste comprehensive treatment and utilization method
The invention discloses a tailing solid waste comprehensive treatment and utilization method which comprises the following steps: weighing the following components in percentage by mass: 92-98% of solid waste tailings and 2-8% of a P-type gelling agent, and the sum of the mass percentages of the components is 100%; adding water, stirring to form a mixture, controlling the water content to be 5-10% after stirring, and controlling the stirring time to be 2-5 minutes; when the weighed components are mixed by adding water, controlling the initial setting time of the mixture to be 3.0-7.0 hours from the beginning of mixing by adding water to the end of forming; compacting or rolling a mixture mixed by adding water to prepare a test block or a pavement base layer with a preset specification, performing wet water maintenance for 5-15 days, and controlling the maintenance temperature to be greater than or equal to 5 DEG C; the method has the advantages that various tailings can be treated into road building materials capable of being used for road pavement base layers, the tailing treatment amount is large, aggregate does not need to be additionally added, and the obtained materials can be used for construction of structures of municipal engineering and water conservancy protection engineering.
一种尾矿固废综合处理利用方法，包括称取以下组分：固废尾矿92～98%，P型胶凝剂2～8%，上述组分的质量百分比之和为100%；加水拌合成混合料，拌和后的控制含水率为5%～10%，拌合时间控制在2～5min；上面称好的组分加水拌合时，从加水拌合开始到成型结束，混合料的初凝时间控制在3.0～7.0h；将加水拌合成的混合料击实或碾压做成预设规格试块或路面基层，湿水养护5～15d，养护温度控制应≥5℃；本申请的方法具有能够将多种尾矿处理变成可以用于道路路面基层的筑路材料、而且尾矿处理量大，不需要额外添加集料，获得的材料能够用于市政工程、水利防护工程的构造物施工的优点。
