矿山拟采用全尾砂作为充填骨料，为了确定充填料的输送浓度、添加絮凝剂种类及添加量等参数，分别对料浆浓度为68%、70%、72%添加不同添加量的明矾、十二烷基苯磺酸钠及聚丙烯酰胺3种絮凝剂进行沉降对比试验，然后对试验结果进行对比分析，综合澄清液液面下降高度及经济成本考虑，最后确定3种絮凝剂添加量沉降回归模型，经济高效的絮凝沉降参数：较佳的絮凝剂为明矾、明矾添加量为29 g/t及全尾砂料浆浓度为70%。
礦山擬採用全尾砂作為充填骨料，為瞭確定充填料的輸送濃度、添加絮凝劑種類及添加量等參數，分彆對料漿濃度為68%、70%、72%添加不同添加量的明礬、十二烷基苯磺痠鈉及聚丙烯酰胺3種絮凝劑進行沉降對比試驗，然後對試驗結果進行對比分析，綜閤澄清液液麵下降高度及經濟成本攷慮，最後確定3種絮凝劑添加量沉降迴歸模型，經濟高效的絮凝沉降參數：較佳的絮凝劑為明礬、明礬添加量為29 g/t及全尾砂料漿濃度為70%。

Flocculant settlement tests are performed by adding different amounts of flocculation agents, alum, sodium dodecylbenzenesulfonate and polyacrylamide into varied slurry concentrations, 68 %, 70 % and 72 %, respectively, to determine the transport solubility of filling material, type and adding flocculant amount. The results are compared and analyzed by taking the supernatant liquid drop height and economic cost into account. The settlement regression models for the three kinds of flocculant addition amounts are determined by working out the economic efficiency of flocculation and sedimentation parameters. The results show that the best flocculant is alum with additive amount of 29 g/t and the total tailings concentration is 70%.
