This invention belongs to the field of mineral processing technology and discloses a beneficiation method for hematite ore concentrate by strong magnetic separation. Ultra-high-speed stirring at 3000 r / min to 4000 r / min is used for desorption of inhibitors, providing clean adsorption active sites for the anionic collector. Oleic acid-modified imidazoline methyl sulfate ammonium is used instead of the traditional collector, dodecylamine. Oleic acid-modified imidazoline quaternary ammonium salt compound, with a C18 unsaturated oleic acid group molecular structure, generates strong steric hindrance compared to the acyclic, large-volume groups of dodecylamine. This prevents the reagent molecules from agglomerating at high density on the bubble surface, thus avoiding the formation of thick, viscous bubbles like with traditional dodecylamine, resulting in stronger fluidity and better foam characteristics. This provides a key guarantee for achieving a stable iron concentrate grade of 66%-70% and a recovery rate of 60%-85%.

This invention provides an aqueous zinc-ion battery electrolyte containing a bifunctional additive of hydroxyl quaternary ammonium salt and methyl sulfate, its preparation method, and its application. The electrolyte is composed of soluble zinc salt, a bifunctional additive containing hydroxyl quaternary ammonium salt and methyl sulfate, and chromatographic water. By using the bifunctional additive containing hydroxyl quaternary ammonium salt and methyl sulfate to modify the traditional aqueous zinc-ion battery electrolyte, the zinc anode is protected, and the cycle life of the zinc anode under high utilization efficiency conditions is significantly improved. The hydroxyl groups in the hydroxyl quaternary ammonium salt additive can form hydrogen bonds with water molecules in the zinc ion solvation shell. At the same time, the quaternary ammonium salt has strong electronegativity to constrain the surrounding water molecules, inhibiting water molecule activity and reducing the occurrence of hydrogen evolution reaction. The methyl sulfate additive can be adsorbed on the surface of the zinc anode, inducing selective deposition of Zn along the (002) crystal plane and inhibiting dendrite formation. The two additives, hydroxyl quaternary ammonium salt and methyl sulfate, work synergistically to effectively improve the utilization efficiency of the zinc anode and the cycle life of the aqueous zinc-ion battery.
