The invention relates to a fluorite ore sorting device and method and belongs to ore sorting devices and methods. The device comprises a coarse grain easy flotation ore rapid flotation device, a filling flotation device and a fine grain hard flotation ore strengthening collection device. The rapid flotation device comprises a flotation column, a lower guide pipe, a reflection false bottom, an annular sleeve, a foam collection tank and a bubble generator. The strengthening collection device comprises a cone, an inverted cone, a bubble generator, an ore pulp circulation pump and a lower inverted cone. The filling flotation device is a column segment between the rapid flotation device and the strengthening collection device and is provided with filler. The method includes the steps that feed ore is pressurized through a feed pump, subjected to the reaction in the bubble generator and the coarse grain easy flotation ore rapid flotation in the flotation column through the lower guide pipe, medium floatable ore is placed in the filling flotation device for further flotation sorting, and fine grain hard flotation ore is placed in the strengthening collection device for further sorting. The fluorite ore sorting device and method is high in mineralization efficiency, flotation speed and sorting efficiency and solves the problem that how to integrate the sorting of coarse grain easy flotation ore and fine grain hard flotation ore in one.
