Abstract

Apparatus for the continuous refining of metals, such as, lead, tin, comprising a distillation column built up of identical boxes set up one upon another and forming evaporation stages along which the metal flows off sequentially in the form of a thin film. Extending through all the column boxes are preferably three graphite heater rods set up in a row, the heater being preferable connected in a three-phase electric circuit. The heating of the metal film is conducive to the distillation of impurity vapors, referred to as volatilized impurities, flowing to condensing shields.
