Abstract

A procedure for the continuous extraction of copper and copper compounds contained in lead, by liquefaction in a lead bath in which there is a temperature drop from top to bottom, characterized in that the liquefaction process takes place in a column of vertical lead, in which the contaminated lead is made to enter at its upper part, the fall of temperature in the column being adjusted to a temperature in the upper part of 800 to 950º, preferably of 830 to 860º C, and a temperature in the background of approximately the eutectic temperature, and because the decoped lead is removed from below, while a copper-rich phase is extracted from the surface of the lead column.
