According to the method, four sedimentation basins are established, and a high-pressure gas blowing apparatus and a solar energy heating apparatus are provided. The end of a gas blowing pipe put into the high-pressure gas blowing apparatus is artificially inserted from the upper end to the lower end of each sedimentation basin for successive pressurized gas blowing, superfluous water in the basin floats to the surface of the sedimentation basin along with the gas flow in the basin, and standing is performed for a period after all clear water at the basin surface is completely discharged; and when standing is performed, residual water is evaporated under the heating effect of the solar energy heating apparatus and the heat conduction effect of iron concentrate self, and when the water content of the iron concentrate powder in the basin reaches 10% or lower, the product can be cleared and discharged. The method realizes target that the iron concentrate powder in the sedimentation basin of a small / medium-size iron-mine ore dressing plant is rapidly dewatered as well as the investment is less, and the final product is low in water content.
