摘要琥珀酸磺酸盐是锡石浮选的最佳捕收剂之一。浮选结果表明，磺基琥珀酸酯对锡石具有较强的捕收性和选择性。还考察了抑制剂、金属离子等因素对锡石浮选的影响。通过Zeta电位、红外光谱、XPS和分子轨道理论对磺基琥珀酸酯浮选机理的研究表明，磺基琥珀酸酯的羧基和磺酸基中的氧与锡石表面的活性锡位发生化学键作用，在锡石表面形成多环络合物。
ABSTRACT Sulphosuccinamate is one of the best collectors used for flotation of cassiterite. The flotation results show that sulphosuccinamate displays strong collection and selectivity for cassiterite at lower dosage. The influence of other factors, such as depressants and metal cations on the cassiterite flotation has also been investigated. Studies on the mechanism of flotation with sulphosuccinamate, through zeta potential, infrared spectrometer, XPS and molecular orbital theory indicate that multi-ring chelates are formed on the cassiterite surface through chemical bonding between active stannum sites and oxygens in carboxylic and sulphonic acid groups of sulphosuccinamate.
