| 摘 要： | 铝硅酸盐矿物是层状硅酸盐矿物,破碎后晶体端面荷电是表面原子的选择性吸附和解离而成,并随pH变化而变化,其层面荷电为金属离子的晶格取代造成,荷永久负电荷,不随溶液pH值变化而改变.阳离子捕收剂是铝硅酸盐矿物捕收剂的设计首选.多胺类药剂与十二胺相比增加了吸附活性点,浮选性能得到改善.有关参数的计算结果说明多胺类药剂是比十二胺更佳的铝硅酸盐矿物捕收剂.浮选试验也证实这一结论.

| Abstract: | The kaolinite, pyrophyllite and illite are samdwich silicate minerals. After broken up, the electric charge in the crystal side has changed with pH changing, and the electric charge in the crystal surface is immobilized because of crystal lattice substitution. The cation collectors are preferred to the Al-Silicate minerals collectors. Comparing to DDA, the catching capability of the diamines have been improved. |

| Keywords: | Al-Silicate minerals reverse fiotation elements of the electric charge in the crystal exterior the cation collectors the diamine |
