ABSTRACT Ionic liquids (ILs) are finding applications in various domains of physical sciences these days. They are used in organometallic syntheses, catalysis, electrochemistry, fuel, solar cells, lubricants, enzyme, separation technologies, nanomaterials, tissue preservation etc. However, the application of ILs in the area of mineral processing is minimal. Considering the potential use of ILs in metal extraction and many chemical reactions, these compounds may play an essential role in the selective recovery of mineral values from the ores having multiple mineral phases. In this paper, the application of some selected ILs in the mineral flotation studies has been reviewed. The interaction of ILs with the desired mineral phases has been described vide the evidence from zeta potential, X-Ray Diffraction, X-Ray Photoelectron Spectroscopy (XPS), Fourier Transform Infra-Red (FTIR) spectroscopy, Raman spectra as well as molecular modeling studies. The results of the studies carried out on low-grade iron ores have indicated that ILs under investigation can be compared with the conventional iron ore collectors such as dodecylamine.

季铵基离子液体在矿物浮选中的应用综述

摘要 如今，离子液体 (IL) 正在物理科学的各个领域中得到应用。它们用于有机金属合成、催化、电化学、燃料、太阳能电池、润滑剂、酶、分离技术、纳米材料、组织保存等。然而，离​​子液体在矿物加工领域的应用很少。考虑到离子液体在金属提取和许多化学反应中的潜在用途，这些化合物可能在从具有多种矿物相的矿石中选择性回收矿物价值方面发挥重要作用。本文综述了一些选定的离子液体在矿物浮选研究中的应用。ILs 与所需矿物相的相互作用已通过 zeta 电位、X 射线衍射、X 射线光电子能谱 (XPS)、傅里叶变换红外 (FTIR) 光谱、拉曼光谱以及分子建模研究。对低品位铁矿石进行的研究结果表明，所研究的离子液体可以与十二胺等传统铁矿石捕收剂进行比较。
