Tungsten tailing-based geopolymer curing material and preparation method thereof
The invention belongs to the technical field of heavy metal pollution remediation, and particularly provides a tungsten tailing-based geopolymer curing material which comprises a solid raw material and a liquid raw material, the solid raw materials comprise 40-60 parts of tungsten tailing powder and 40-60 parts of metakaolin; the liquid raw material comprises an alkali activator solution. According to the tungsten tailing-based geopolymer curing material provided by the invention, the activity of metakaolin is excited in an alkaline solution environment, the metakaolin reacts with potential gelling substances in tungsten tailings to form an inorganic high polymer with a net structure, and heavy metal ions are cured, so that short-process, high-valued and high-absorptive building material utilization of tailing resources is realized; and the potential environmental problem of heavy metal ions in the tailings in the stockpiling process is also avoided. The invention also provides a preparation method of the tungsten tailing-based geopolymer curing material, the process is simple, the flow is short, the production cost is low, the treatment of the tailings containing the heavy metals can be effectively realized, and the efficient curing of the heavy metal ions is realized.
本发明属于重金属污染修复技术领域，具体提供了一种钨尾矿基地聚物固化材料，包括固态原料和液态原料；所述固态原料包括40‑60份钨尾矿粉，40‑60份偏高岭土；所述液态原料包括碱激发剂溶液。本发明提供的这种钨尾矿基地聚物固化材料利用偏高岭土在碱溶液环境中活性被激发，与钨尾矿中潜在胶凝物质反应，形成网状结构的无机高聚物，固化有重金属离子，不仅实现了尾矿资源的短流程、高值化、高消纳建材化利用，还避免了尾矿中重金属离子在堆存过程中存在的潜在环境问题。本发明还提供了钨尾矿基地聚物固化材料的制备方法，工艺简单、流程短、生产成本低，可有效实现对含重金属尾矿的处理，实现对重金属离子的高效固化。
