摘要
研究了Ａｅｒｏｓｏｌ－２２（烷基磺化琥珀酰胺酸盐）对锡石的浮选行为以及浮选调整剂如稻草纤维素、水玻璃对石英、方解石的抑制作用。还考察了金属阳离子和中性油对锡石浮选的影响。结果表明，Ａｅｒｏｓｏｌ－２２是锡石的良好捕收剂，具有捕收力强、用量低等特点。Ａｅｒｏｓｏｌ－２２与锡石作用机理研究指出，Ａｅｒｏｓｏｌ－２２在锡石表面是通过羧酸和磺酸基中的氧原子与锡石表面的活性质点Ｓｎ４＋键合，并且形成了０。
Flotation behaviour of cassiterite,quartz,calcite with collector of tetrasodium octadecyl sulfosuccinamate(Aerosol-22)and depressants of carboxy-methyl cellulose(CMC),sodium silicate,and influence of metal cations and neutral oils have been investigated.The result shows that Aerosol-22 is an optimum collector for cassiterite because of its strong collection and lower dosage.Study on interaction mechanism,with modern technologies such as zeta potential,infrared spectrometry,X-ray photoelectron spectroscopy and molecular orbit theory,demonstrates those oxygen atoms in carboxylic and sulfonicacid groups bond with the surface active sites(Sn) of cassiterite,and form a multi-cycle chelate on the surface.
