Title (EN) A METHOD FOR RECOVERING LEAD FROM A LEAD-CHLORIDE RAW MATERIAL
(FR) METHODE DE RECUPERATION DU PLOMB A PARTIR D"UN MATERIAU BRUT DE CHLORURE DE PLOMB
Abstract: front page image
(EN)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).
(FR)Un procede de recuperation du plomb a partir de materiaux bruts de chlorure de plomb obtenus particulierement par hydrometallurgie consiste a reduire lesdits materiaux bruts avec un gaz de reduction. Le procede est conduit de maniere appropriee avec de l"hydrogene ou de l"ammoniac dans un reacteur a colonnes (1) a contre-courant, le chlorure de plomb liquide etant en contact avec le gaz de reduction, a une temperature appropriee situee entre 900 et 970 C. Le reacteur a colonnes (1) peut comprendre une pluralite de reacteurs (22, 26, 30) couples en serie. Le plomb metal forme (5) sort par le fond (15, 35, 36, 37) en coulant des colonnes respectives. Le chlorure de plomb qui n"a pas reagit (6) et, si desire les gaz de procede peuvent etre recircules (8, 9, 10, 7 et 19, 16 respectivement).
