分别研究了一水硬铝石和高岭石的浮选行为及混合矿的分选,结果表明:仅以油酸钠作捕收剂可较好实现给矿A/S在2.53~4.96范围内的一水硬铝石和高岭石混和矿的正浮选分离;以十二胺作捕收剂酸性介质条件及十二胺作捕收剂,ATNO作抑制剂中性介质条件下也可较好实现给矿A/S为2.53~4.96范围内时一水硬铝石和高岭石的反浮选分离,精矿 A/S均在 11 以上.图4,表4,参8. The flotation behavior of diaspore and kaolinite and the separation of mixed ore were studied respectively. The results showed that only the use of sodium oleate as collector can better achieve the A / S of 2.53 ~ 4.96 A diaspore and kaolinite mixed flotation positive flotation; dodecylamine as a collector acidic medium conditions and dodecylamine as a collector, ATNO inhibitor as a neutral medium conditions can be better achieved When the ore A / S is in the range of 2.53 ~ 4.96, the reverse flotation separation of diaspore and kaolinite is carried out, and the concentrate A / S is above 11.
