Abstract

The invention discloses a charged magnetic hydrophobic material and a preparation method and application thereof in separation of micro-fine-particle minerals. The material includes magnetic particlesand a metal organic complex loaded on the surface, has strong magnetism, is positively charged on the surface, and has high electrostatic adsorption capacity for anions and high physical adsorption performance for hydrophobic micro-fine-particle minerals, and therefore, after micro-fine-particle minerals in ore pulp are subjected to surface hydrophobic and anion modification, the micro-fine-particle minerals can be adsorbed and agglomerated by utilizing the material, then the micro-fine-particle minerals are efficiently separated from gangue minerals through magnetic separation, thus solvinga difficult problem of separation and purification of ultrafine minerals. A preparation process of the charged magnetic hydrophobic material is simple and cheap and meets industrial production requirements.
