氢化松香酯基阳离子捕收剂M--N的合成及浮选性能
Synthesis and flotation performance of a hydrogenated rosin ester-based cationic collec-tor M--N
摘要
Abstract
This paper optimized the synthesis conditions such as molar ratio, temperature and time by examining quartz recovery and the active content of quaternary ammonium. The reverse-flotation results using roast-magnetite separation of Jiugang iron show that a concentrate with a grade of 56. 54% and a recovery rate of 77. 33% are obtained using M- N as collector. At 5- 30 ℃ , the reverse flotation result is stable, as well as the low-temperature resistance is excellent. Selectivity of M- N is superior to the traditional collec-tor dodecylamine and ether amines. The result of Zeta potential and infrared spectroscopy reveals that the successful separation effect of M- N is due to electrostatic adsorption and hydrogen bonding on quartz.关键词
