摘要：
According to one embodiment, a fluorine recovering apparatus includes a precipitating device allowing fluoride ion-containing water to react with calcium source to form precipitate, a mixing tank mixing a filter aid including particles of a magnetic material having a diameter of 0.5 to 5 μm with a dispersion medium to produce slurry, a filter aid feeder to the mixing tank, a solid-liquid separator with a filter depositing a filter aid layer, and depositing the precipitate on the filter aid layer, a cleaning mechanism removing the filter aid and the precipitate, a separating tank separating the filter aid and the precipitate, and a returning mechanism returning the filter aid to the filter aid feeder.
