The pH value is different in different beneficiation steps, for example, in the roughing and the concentrating, the proper pH value at higher grade is obtained through experiments. After kerosene is added in the flotation process, the quantity and the size of foam are moderate, and a foam layer is stable. The addition of isooctanol phosphate increases the emulsification of the collecting agent and the binding speed with raw ore, so that the flotation speed is obviously accelerated, and the dosage of the reagent is obviously reduced under the condition that the recovery rate and the grade are almost the same.
The invention also aims to provide a preparation method of the ilmenite flotation collecting agent, which has the advantages of simple process, easy control of operation, wide raw material source, low cost, safety, environmental protection, high product recovery rate and easy realization of industrial production.
