A mixture of two acids (H₂SO₄, HCl) was used to enhance the acid leaching of vanadium (V) and gallium (Ga) from red mud, and the effects of key parameters on the leaching rates of V and Ga were investigated, including volume ratio of two acids, acid concentration, reaction time, leaching temperature and liquid-to-solid ratio. The results show that under the following conditions, including two acids in a volume ratio of 1∶1, acid concentration of 28.89%, liquid-to-solid ratio of 9, reaction time of 60 min and leaching temperature of 120 ℃, the leaching rates of V and Ga can reach 90.65% and 97.30%, respectively. X-ray diffraction (XRD) and thermodynamic analyses indicate that muscovite, hematite and perovskite in red mud are dissolved to some extent during the acid leaching process, and vanadium and gallium exist in different valence states in the leachate. It is concluded that acid leaching can effectively promote dissolution of minerals and release of valuable metals.

采用双酸（H₂SO₄，HCl）复配强化酸浸的方法提取赤泥中的钒、镓，考察了双酸体积配比、酸浓度、反应时间、浸出温度以及液固比对钒、镓浸出率的影响。结果表明，在双酸体积配比1∶1、酸浓度28.89%、液固比9、反应时间60 min、浸出温度120 ℃条件下，钒浸出率为90.65%，镓浸出率为97.30%。X射线衍射分析和热力学分析结果表明，在酸浸过程中，赤泥中的白云母、赤铁矿和钙钛矿均被一定程度溶解；钒和镓分别以钒酸盐和镓离子形式存在于酸浸液中，表明酸浸有效促进了矿物的溶解及有价金属的释放。
