【摘要】 本文介绍了新型锡石捕收剂——烷胺双甲基膦酸(代号浮锡灵)浮选锡石的单矿物试验、人工混合矿分离和天然锡石矿泥的浮选试验结果。试验表明,浮锡灵的捕收力强、抗矿泥干扰性能好,对-5微米的锡石微泥具有强力的捕收作用。应用浮锡灵浮选广西栗木锡石矿泥,获得了优于苄基胂酸的选矿效果。 通过红外光谱、ζ-电位以及吸附量的测定,研究了浮锡灵对锡石的作用机理。结果表明,浮锡灵在锡石表面的吸附是化学吸附。更多还原

【Abstract】 This paper reports the cassiterite flotation of pure cassiterite, synthetic mixtures and natural tin slimes with a new series of cassiterite collectors——alkylamino-di(mothylphosphonic acid) compounds (named Fuxilin). It has been showed that Fuxilin has a powerful collection to microgranular cassiterite and has a good capability to overcome the interference of slimes. Fuxilin is superior to benzyl arsonic acid to float Limo tin slimes.The adsorption mechanism of Fuxilin on cassiterite has been studied by the determination of the infrared spectra, the Zata potential and the amount of adsorption It has been indicated that Fuxilin is chemically absorbed on the surface of cassiterite.更多还原
