Abstract

A process for recovering lead from lead chloride raw materials obtained particularly hydrometallurgically, by reducing said raw materials with a reducing gas. The process is suitably effected with hydrogen or ammonia in a column reactor (1) in counterflow, liquid lead chloride being contacted with the reducing gas, suitably at a temperature between 900 and 970`C. The column reactor (1) may comprise a plurality of reactors (22, 26, 30) coupled in series. Formed lead metal (5) is tapped-off from the bottom (15, 35, 36, 37) of respective columns. Non-reacted lead chloride (6) and optionally purified process gases can be recirculated (8, 9, 10, 7 and 19, 16 respectively).
