Method for building drainage ditch by utilizing flotation phosphate tailings
The invention discloses a method for building a drainage ditch by utilizing flotation phosphate tailings, and relates to the technical field of resource utilization of the flotation phosphate tailings. The filter-pressed flotation phosphate tailings, the gel material, the coarse aggregate, the water reducing agent, the polypropylene fiber and the water are uniformly mixed to prepare slurry, and the drainage ditch is built through pouring and plastering. More than half of the raw materials use the flotation phosphate tailings, the phosphate tailings are fully consumed, solid waste recycling is achieved, fine sand is replaced, and the problem of shortage of the fine sand is solved; mineral powder, clinker, calcium oxide, calcium chloride, anhydrous sodium sulfate, calcium sulfate dehydrate and sodium silicate are compounded to obtain a gel material, ordinary cement is replaced, rapid solidification of the superfine flotation phosphate tailings is achieved, the compressive strength of the superfine flotation phosphate tailings is improved, and the cost is lower.
本发明公开了一种利用浮选磷尾矿修建排水沟的方法，涉及浮选磷尾矿资源化利用技术领域。将压滤后的浮选磷尾矿、凝胶材料、粗骨料、减水剂、聚丙烯纤维、水混匀后制备成料浆，通过浇筑、抹面修建排水沟。原料中超过一半使用浮选磷尾矿，充分消耗磷尾矿，实现固废再利用，并替代细砂，解决了细砂紧缺的问题；使用矿粉、熟料、氧化钙、氯化钙、无水硫酸钠、二水硫酸钙、泡花碱进行复配得到凝胶材料，替代普通水泥，实现超细浮选磷尾矿的快速固结，提高其抗压强度，且成本更低。
