PROBLEM TO BE SOLVED: To provide a recovering method of bottom dross in galvanization having good efficiency and workability. SOLUTION: A frame body where a filter having 10-30 mesh is inserted in a frame in a attachable/detachable manner, is disposed on galvanizing bath surface and also, a pump is dipped into galvanizing bath and the bottom dross is sucked from a sucking port by using the pump and transported into the filter to recover the bottom dross. It is desirable to hold the temperature of the dross in the filter and molten zinc to 350-460 deg.C. Further, as the pump, a gas-lift pump can be used. Then, the piping between the pump and the sucking port is desirable to be a bent pipe. Further, at least a part of the frame body is dipped into the galvanizing bath and thereafter, the frame body is pulled up above the galvanizing bath surface and this frame body can be held there.
