Abstract
A housing has a pair of chambers separated by a vertical wall. A hearth is on one side of the wall in the housing and is adjacent to an orifice which allows a stream of material, such as molten metal to pass from one chamber to the other. A gas is caused to flow through the orifice counter to the material flow by placing the other chamber at a higher fluid pressure than the one chamber. A blower coupled to the chambers provides the differential pressure. Molten metal is collected in a crucible in the other chamber. The gas flow moves through the orifice and forces impurities on the surface of the material to flow in reverse in the one chamber before the flow passes through the orifice.
