PROBLEM TO BE SOLVED: To ensure original effects in a high-accuracy flotation region while suppressing a great increase in cost. SOLUTION: Between a high-accuracy floating suction mixing part 5 having a relatively fixed floating amount and a low-accuracy floating table 3, a porous floating part 4 is provided having medium accuracy. A difference in accuracy between flotation on the floating suction mixing part 5 and flotation on both sides is therefore reduced. Thus, high-accuracy flotation is less influenced by low-accuracy flotation. The provision of the porous floating part less increases cost than the expansion of the floating suction mixing part 5.
