补充资料:选择性絮凝
      用絮凝剂将溶液(通常为水溶液)中悬浮的微粒(例如小于30μm)选择性地聚集起来,形成尺寸较大的絮团的过程。用于分选微细颗粒的矿物原料;也可与浮选组成联合流程。这是20世纪60年代发展起来的一种分选微细颗粒矿物的有前途的新工艺。
  
  絮凝剂有天然的及合成的两类。天然絮凝剂如蛋白质、树胶、淀粉等。合成絮凝剂为带有极性基团的有机单体聚合而成的线状聚合物,如聚丙烯酰胺、水解聚丙烯酰胺等。按极性基团的性质,絮凝剂有阴离子型、阳离子型及非离子型。因具有极性基团和线状分子链,故能吸附于固体颗粒上;并能在所吸附的颗粒间架桥连接,将若干微细颗粒聚集起来,形成尺寸较大的絮团。后者能以较快的速度在悬浮液中降落。
  
  选择性絮凝是利用含有能选择性地吸附于某种矿物(例如淀粉对赤铁矿)颗粒表面上的絮凝剂,使这种矿物微细颗粒絮凝而沉降,而其他矿物(例如石英)微细颗粒因事先加入分散剂(例如水玻璃加氢氧化钠),仍保持悬浮分散状态,从而可用沉淀法或上升水流法将两者分开。
  
  要达到选择性絮凝,须考虑絮凝剂极性基团的种类及其物理化学性质,矿物表面的化学性质,溶解度及其他物理性质,水溶液中存在的电解质种类及浓度,pH值及流体动力因素(搅拌强度及时间)的影响等。
