In acid pulp, the depressing abilities of reagents on diaspore are in the order of hydroxamic acid starch＞dialdehyde starch＞carboxymethyl starch＞cationic starch＞primary starch. In addition, hydroxamic acid starch and carboxymethyl starch can activate kaolinite without influence on the recoveries of pyrophyllite and illite, so the two reagents have great potential and prospect to be the depressant of diaspore and the activator of kaolinite in bauxite reverse flotation.(3) By oximation of the copolymer of acrylamide and methyl acrylate, hydroxamic acid polyacrylamide is synthesized.

3对丙烯酰胺和丙烯酸甲酯的共聚物肟化制得氧肟酸聚丙烯酰胺，将它同非离子聚丙烯酰胺、阴离子聚丙烯酰胺、阳离子聚丙烯酰胺和两性聚丙烯酰胺分别应用于四种矿物的单矿物浮选试验，结果显示，改性聚丙烯酰胺对一水硬铝石、高岭石和伊利石均具有活化作用，其中，药剂对高岭石的活化最强，使它的回收率在整个pH值范围达到80％左右，在一定pH条件下超过一水硬铝石的回收率，解决了高岭石难浮选的问题。
