摘要: 针对堆积型铝土矿开发应用过程中洗矿尾矿固液分离难题,在应用压滤脱水技术处理铝土矿微细尾矿的试验研究基础上,开展铝土矿尾矿泥的压滤脱水半工业―工业试验研究,探讨压滤机滤室腔型、滤布、入料浓度和助滤介质等因素对矿泥压滤效率的影响。研究发现压滤机滤腔结构、滤室厚度等制造参数对尾矿泥压滤脱水效率有显著影响,滤布的透气、滤水性能对压滤生产影响较大,入料浓度与压滤效率呈显著的正相关关系,添加改性助滤剂有利于提高压滤效率和降低滤饼含水率。该研究可为完善压滤生产技术,寻求经济合理的配套生产工艺、设备,实施大规模工业化的压滤生产提供科学依据。这种提升压滤效率和降低处理成本的方法途径探索,对矿山尾矿及其他难处理物料的固液分离具有较好的借鉴价值。
