摘要： In order to separate metals and/or metal alloys of different melting points from one another, a mixture of these metals and/or metal alloys is brought to a temperature at which the metal or the metal alloy of relatively low melting point is molten and the metal or the metal alloy of relatively high melting point is in the solid state. The solid constituents are separated from the melt, use being made of washing column with at least one filter which withstands the temperature of molten metal. Each of the filters is arranged in the wall of a separate pipe which extends through the washing column. The mixture is fed to one end of the washing column and moves along the pipe or pipes, towards means arranged at the opposite side of the washing column for removing solid crystalline material. The melt passes via the filter or filters into the pipe or pipes, and flows in countercurrent to the mixture situated on the outside of the pipe or pipes, towards a melt discharge. A suspension zone situated in an upper part of the washing column changes into a packed bed of crystals. At the bottom of the washing column, the crystals are washed in countercurrent with their own recirculated melt.
