Design and Synthesis of Collectors for Flotation of Aluminosilicate Minerals and Flotation Mechanism
摘要
Abstract
The gangues in bauxite are mainly aluminosilicate minerals such as kaolinite,il-lite and pyrophyllite. Reverse flotation is adopted to remove silicon, i. e. , these gangure minerals are floated using suitable collectors. Aimed to some bauxite mine,and based on a-nalysis of crystal model of kaolinite using Curis2 software,Polyamines collectors DN12 were designed and synthetized from two aspects of mineral group and non-polar group in the pa-per. The effects of this new collectors on flotation of aluminosilicate minerals and the flota-tion mechanisms were studied by flotation experiments,chemical calculation of flotation so-lutions,zeta potential,and infrared spectrum,respectively. The new collectors have a better effectiveness for catching aluminosilicate minerals than conventional collectors,and the pH ranges of effective flotation are 4~10. The action of DN12 on aluminosilicate minerals was mainly electrostatic adsorption,and also hydrogen bonding which increase the catching ca-pacity to minerals.关键词
