摘要

An improved method and apparatus for removing dross from a lead-refining pot. Dross is removed from molten lead during its refining by scraping the dross by means of a rake up a ramp fitted to the rim of the refining pot, a baffle being placed to trap dross in front of the ramp. The rake may be operated manually or by means of a power operated device.
