Based on investigation of the influence mechanisms of acid and alkaline corrosion for flotation separation of lepidolite and feldspar, efficient separation of lepidolite and feldspar in different particle size fractions was achieved by flotation with surface dissolution and collector interaction. It is found that in flotation process, alkaline corrosion can promote the separation of lepidolite and feldspar more effectively than acid corrosion. Under optimal conditions, lepidolite concentrates in size fraction of 38-74 μm and-38 μm are obtained with recoveries of Li₂O at 92.54% and 83.20%, respectively. The effects of acid and alkaline corrosion on the wettability, morphology, reagent adsorption and electrical potential of the mineral surface were explored by contact angle measurements, high-speed camera observations, SEM, AFM, XPS, infrared spectroscopy and zeta potential analyses. Results show that alkaline corrosion, due to its distinct mechanisms at the surfaces of lepidolite and feldspar, can promote the separation between them; whereas acid corrosion has no selectivity for two minerals. Besides, both acid and alkaline corrosion are independent of particle size of minerals.

研究了酸蚀和碱蚀作用对锂云母和长石浮选分离的影响机制，通过表面溶蚀和捕收剂作用实现了不同粒级锂云母与长石的高效浮选分离，结果显示，碱蚀作用比酸蚀作用更能促进锂云母和长石的浮选分离，在适宜条件下，38~74 μm粒级和-38 μm粒级锂云母精矿的Li₂O回收率分别为92.54%和83.20%。通过接触角测试、高速摄影机观测以及SEM、AFM、XPS、红外光谱测试等研究了酸蚀和碱蚀对矿物表面润湿性、形貌、药剂吸附及电位的影响，结果表明，碱蚀作用对锂云母和长石表面不同的作用机制促进了两种矿物的浮选分离，而酸蚀作用对矿物表面的溶蚀没有选择性；两种溶蚀作用的效果均不受矿物粒级的影响。
