A aliquat 336/lactic acid deep eutectic solvent was used for the reverse flotation of magnetite for the first time. The deep eutectic solvent increased the total iron content of the feed ore from 53.02% to 66.80%, which was better than dodecylamine. The FTIR, zeta potential, contact angle, and XPS showed that the deep eutectic solvent was easilier adsorbed on the quartz surface and improved its hydrophobicity, compared with magnetite. Thus, the deep eutectic solvent was a promissing flotation collector agent, guiding the design of the multifunctional flotation collector agent.

深共熔溶剂在石英和磁铁矿分离中的新应用

首次使用aliquat 336 /乳酸深共熔溶剂进行磁铁矿的逆浮选。深共熔溶剂将进料矿石中的总铁含量从53.02％提高到66.80％，优于十二烷基胺。FTIR，ζ电位，接触角和XPS表明，与磁铁矿相比，深共晶溶剂更容易吸附在石英表面上，并改善了其疏水性。因此，深的低共熔溶剂是一种理想的浮选捕收剂，指导了多功能浮选捕收剂的设计。
