The invention relates to a water washing method and device for purifying calcite ores through a rotating drum. The calcite ores are fed from the low end of the rotating drum and discharged from the high end of the rotating drum. A clear water inlet pipe and a water returning inlet pipe which penetrate through the rotating drum continuously supply returning water to spray from a drum low end feeding inlet to the middle of the drum meanwhile continuously supply clear water to spray from a drum high end discharging outlet to the middle of the drum, so that the calcite ores are washed in a mode of reverse flow with the washing water. By adopting the ore washing method of low inlet and high outlet and reverse flow with the washing water, pollution caused by the fact that waste water flows out with the calcite ores in the same direction is avoided, and by adjusting the rotating speed of the drum as well as the water pressure and amount, the yield of water washed calcite can be increased, and the required indexes of
