摘要

本文研究了铝(Al(III))和铁(Fe(III))离子对油酸捕收剂体系中钾长石(k -长石)浮选效率的影响及其机理。本研究通过微浮选实验、溶液化学计算、zeta电位测量以及FT-IR和XPS分析，证明了Al(III)和Fe(III)离子可以通过改变k -长石的表面电荷、键合性质和吸附方式，显著提高k -长石的浮选回收率。研究还建立了Al(III)和Fe(III)活化钾长石浮选的吸附模型，揭示了金属离子水解产物和油酸钠在疏水配合物形成中的协同作用。

The effect of Al(III) and Fe(III) ions on the flotation behavior of k-feldspar with sodium oleate as the collector

The present study investigates the effects and mechanisms of aluminum (Al(III)) and iron (Fe(III)) ions on the flotation efficiency of potassium feldspar (K-feldspar) within oleate collector systems. The study employs micro-flotation experiments, solution chemistry calculations, zeta potential measurements, and FT-IR and XPS analyses to demonstrate that Al(III) and Fe(III) ions can significantly improve the flotation recovery of K-feldspar by altering its surface charge, bonding properties, and adsorption modes. The study also develops adsorption models for the flotation of K-feldspar activated by Al(III) and Fe(III), revealing the synergistic impacts of metal ion hydrolysis products and sodium oleate in the formation of hydrophobic complexes.
