研究了Gemini12-4-12对一水硬铝石和高岭石的浮选行为,在中性介质(pH7～pH8)下,对一水硬铝石与高岭石的反浮选分离作了初步探讨。浮选结果表明:Gemini12-4-12在广泛的pH范围内对一水硬铝石和高岭石具有很强的捕收能力,在中性体系(pH7～pH8)及浓度3.0×10-4mol.l-1时,对一水硬铝石和高岭石的浮选回收率达到95%以上;在可溶性淀粉浓度为200mg/l的条件下,一水硬铝石全部被抑制,而且两种矿物回收率相差达70%以上,并且通过人工混合矿试验,对不同A/S的一水硬铝石和高岭石人工混合矿取得很好的分离效果。
The flotation behavior of Gemini12-4-12 on diaspore and kaolinite was studied. In the neutral medium (pH7 ~ pH8), the flotation separation of diaspore and kaolinite was preliminary studied Discussion. The flotation results show that Gemini12-4-12 has a strong ability to collect diaspore and kaolinite in a wide range of pH values in a neutral system (pH7 ~ pH8) and a concentration of 3.0 × 10-4mol. l-1, the recovery rate of flotation for diaspore and kaolinite reached more than 95%; in the condition of soluble starch concentration of 200mg / l, all the diaspore was inhibited, and the recovery of the two minerals Rate difference of more than 70%, and through the artificial mixed ore test, for different A / S diaspore and kaolinite artificial mixed ore to obtain a good separation effect.
