Abstract
Développement du brevet principal qui est relatif à un procédé pour l'extinction d'antimoine à partir de minerais en contenant, par traitement desdits minerais à une température de 450 à 600 degrés C, à l'aide de chlorure de calcium en atmosphère oxydante et en présence d'anhydride sulfureux. On utilise un minerai oxydé d'antimoine, la chloruration au chlorure de calcium s'effectuant directement sur le minerai et conduisant à un chlorure d'antimoine volatil qu'on récupère. Application au traitement de minerais pauvres en oxyde d'antimoine.
