Abstract

Process for the continuous purification of work lead by cooling. Said process is characterized in that liquid work lead is poured into a thermostat cauldron containing liquid metal lead at a temperature lower than 500<o>C approximately and under stirring and in that pulverulent materials accumulating at the surface are recovered. Application to lead metallurgy.
