摘要
聚丙烯酰胺在矿业领域中有着重要地位,广泛用于尾水处理和矿物絮凝。对聚丙烯酰胺类絮凝剂的种类、合成方法、絮凝机理及相关应用进行了综述,分析了此类絮凝剂在矿业领域应用面临的主要问题,指出聚丙烯酰胺应该朝着高效、高选择性、环保、安全和经济的方向深入发展。
Polyacrylamide plays an important role in mining industry and is widely used in tail water treatment and mineral flocculation.In this paper,the types,synthesis methods,flocculation mechanism and related applications of these flocculants were reviewed.The main problems in the application of polyacrylamide flocculants in mining industry are pointed out,and it is expounded that polyacrylamide should be developed deeply in the direction of high efficiency,high selectivity,environmental protection,safety and economy.
