摘要

摘要研究了战略工业矿物萤石在单宁酸(TA)抑制剂的作用下从氟碳铈矿中浮选分离。在本研究中,吸附分析表明TA在氟碳石上的吸附密度大于萤石。zeta电位、傅里叶变换红外光谱(FTIR)和x射线光电子能谱(XPS)证明了TA与萤石或氟碳铈矿在最佳pH条件下同时发生化学吸附和静电吸引,后者还涉及氢键相互作用。此外,微浮选和批量浮选结果表明,在低浓度下,TA可以有效抑制氟碳石,对萤石的影响可以忽略不计,并且TA附着在氟碳石表面阻碍了邻苯二甲酸(PA)作为捕收剂的吸附,而可以吸附在萤石表面。研究结果为氟碳铈矿与萤石的浮选分离提供了坚实的理论基础和有效的指导。

Adsorption of tannic acid as depressant in the flotation separation of fluorite and bastnaesite
ABSTRACT Fluorite, a strategic industrial mineral, was investigated for flotation separation from bastnaesite with tannic acid (TA) as depressant. In this study, the adsorption analysis indicates that the adsorption density of TA on bastnaesite was greater than that of fluorite. The zeta potential, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) provide the evidence that chemisorption and electrostatic attraction occurred simultaneously between TA and fluorite or bastnaesite at optimal pH, the latter also involving hydrogen bonding interactions. Furthermore, the micro-flotation and batch flotation results suggest that TA could effectively depress bastnaesite with a negligible effect on fluorite at low concentrations, and that TA attached to the surface of bastnaesite precluded the adsorption of phthalic acid (PA) as collector, whereas it could be adsorbed on the fluorite surface. These findings offer a robust theoretical foundation and valid guidance for the flotation separation of fluorite from bastnaesite in industrial processes.
