ABSTRACT:
The invention relates to a method for recovering lead from lead chloride raw materials, by reducing the lead chloride with gas in a reaction zone comprising one or more separate reaction chambers. The invention is characterized in that two reduction processes are carried out simultaneously in the reaction zone, namely a reduction of solid or liquid lead chloride and a reduction of gaseous lead chloride. Non-reacted lead-chloride reactants in either of the two reduction processes are caused to take part as a reactant in the other process. The reduction gas is taken from the upper part (2) of the reaction zone (1) and the temperature of the upper part (2) of the reaction zone (1) is lower than the lower part (4) of the reaction zone.
