Flocculating sedimentation is a critical step in the thickening and dewatering of tailings during the backfilling process in mines. A certain iron mine in Liaoning has a complex and diverse mineral composition, with a significant proportion of fine-grained tailings, which poses challenges such as slow sedimentation rates and high overflow turbidity for the flocculating sedimentation process. To study the flocculating performance and sedimentation mechanism of tailings from the iron mine, experiments were conducted using whole tailings as the main test material. Results of natural sedimentation and flocculating sedimentation tests were compared. Single-factor method was combined to carry out flocculant selection tests were conducted, with clarity of the supernatant and sedimentation rate being the main evaluation indicators. Ultimately, 655S flocculant with the best sedimentation effect was selected for subsequent flocculating sedimentation experiments. By adjusting flocculant unit consumption and filling slurry concentration, the effects of these two factors on the performance of slurry flocculation and sedimentation were analyzed separately. When feed concentration was below 20%, the optimal flocculant addition was controlled in the range of 15±5 g/t, with the underflow concentration reaching 62.61%. Findings of this study provided a theoretical basis for improving the quality and efficiency of fine tailings backfilling in similar mines, and had significant practical value and engineering guidance significance.

絮凝沉降是矿山充填过程中尾砂浓密脱水的关键环节。辽宁某铁矿矿物成分复杂多样且细粒级尾砂占比较大，该矿山的絮凝沉降面临沉降速率慢、溢流浊度高等难题。为研究该铁矿絮凝沉降性能及机理，以全尾砂为主要试验材料，开展了自然沉降和絮凝沉降对比试验。试验以上层液澄清度和沉降速率为主要考察指标，结合单因素法开展絮凝剂选型试验，最终选取沉降效果最优的655S絮凝剂开展后续絮凝沉降试验研究。分别分析了絮凝剂单耗和充填料浆浓度这两种因素对絮凝沉降性能的影响。研究结果表明：该铁矿尾砂絮凝沉降入料浓度不超过20%时，絮凝剂最佳添加量控制在15±5 g/t，底流浓度可达到62.61%。本研究结果可为提高类似矿山细粒级尾砂充填质量和效率提供理论依据，具有重要的应用价值和工程指导意义。
