Preparation method of activator for promoting activation effect of ilmenite

The invention relates to a preparation method of an activator for promoting the activation effect of ilmenite, and belongs to the technical field of mineral processing. The activator is prepared fromlead nitrate, potassium permanganate and sodium hypochlorite in a specific ratio, the ratio corresponds to the different pH and varies with the different pH. The order in which the lead nitrate, the potassium permanganate and the sodium hypochlorite are added to a solution is determined by the change in pH. Both the sodium hypochlorite and the potassium permanganate can undergo a redox valence state conversion reaction with surface atoms of the ilmenite and the combination of the sodium hypochlorite and the potassium permanganate synergistically enhances the reaction effect. After the reaction, newly formed ferric iron is more easily hydroxylated than divalent iron to form a more stable Fe-hydroxyl complex, formation of more stable Fe-O-Pb complexes achieved by the Fe-hydroxyl complex andhydroxylated lead ions is
