Cassiterite flotation with sulphosuccinamate collector

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.
