摘　　要：介绍了陕西大西沟菱铁矿选矿废水的特点,研究了外加石灰乳和不同絮凝剂(比如:聚丙烯酰胺、聚合氯化铝、聚合硫酸铁、淀粉、明矾等)配比的絮凝沉降效果。结果表明:添加石灰乳和絮凝剂聚丙烯酰胺处理选矿废水,净化后水质远低于废水综合排放标准《GB8978-1996》一级标准。Directed at the properties of mineral processing wastewater of Daxigou siderite ore m Shanxi prownce, me flocculent sedimentation effect is studied by controlling the rational proportioning of lime milk and different flocculants such as PAM, PAC, SPFS, starch and alum. The result showed quality of the purified water reaches national grade-one standard of wastewater discharge （GB8978 -1996） by adding lime milk and the flocculant PAM to treat the mineral processing wastewater.
