摘要
研究了尾矿高浓度浓缩絮凝剂的选择。无机凝聚剂氧化钙虽然沉降速度较低,但有较好的澄清水；无机高分子絮凝剂碱式氯化铝沉降速度高于前者且有更好的澄清水,而聚丙烯酰胺的絮凝效果最佳,沉降速度最大且有更好的澄清水。现场的矿浆适宜于使用阴离子型聚丙烯酰胺絮凝剂,且有用量少、效率高的特点,在给矿浓度为4%～6%时,絮凝剂用量为5～10g/t。
High concentration flocculating agent for the concentrate of trailings was studied in this paper. Calcium oxide, an inorganic agglomerate medicament, works with a low sedimentation velocity but with a limpid outflow. Alkaline aluminium chloride, an inorganic macromolecule flocculating agent, got a quicker sedimentation velocity and with a better limpid outflow. Polypropylene aeyl amine had the best flocculation effect with the highest sedimentation velocity and a best limpid outflow. Anion polypropylene acyl amine flocculating agent was good for mineral slurries in fieldwork with a low dosage and excellent effect that a flocculating agent dosage of 5 to 10g/t well worked for mineral slurries with a concentration of 4% to 6%.
