【摘要】 通过浮选药剂BET对煤和黄铁矿的表面电位、润湿性、ESCA分析和吸附量测定等方面的研究,揭示了BET与煤和黄铁矿的作用机理,并进行了实际煤样的分选实验.实验结果表明,BET的浮选效果要优于普通煤用浮选药剂,尤其是用于高硫煤的浮选时,它有很强的选择性.更多还原

【Abstract】 The study on the effect of floatation reagent BET on coal and pyrite, which mainly concerned the respects such as surface potential, wettability, ESC A analysis and absorption measurement of coal and pyrite, revealed the mechanism of BET to coal and pyrite. The separation tests of practical samples were carried out. The results manifested that the floatation effect of BET is better than that of other common floatation reagents and has a higher selectivity especially in high-sulfur coal sample floatation.更多还原
