Abstract

La présente invention concerne un procédé de production pour obtenir efficacement une poudre de cobalt au moyen d'un procédé qui augmente l'efficacité de la réaction de réduction pendant la production de la poudre de cobalt à partir d'une solution qui contient un complexe d'acide sulfurique-cobalt-amine. Un procédé de production d'un cristal de germe d'une poudre de cobalt, qui est caractérisé par la conduite séquentielle de : une étape de complexation pour obtenir une solution contenant un complexe d'acide sulfurique-cobalt-amine par ajout d'ammoniac et/ou d'une solution d'un composé d'ammoniac dans une solution de sulfate de cobalt, une étape de mélange pour obtenir une suspension concentrée mélangée par ajout d'un matériau solide dans la solution contenant un complexe d'acide sulfurique-cobalt-amine obtenue dans l'étape de complexation; une étape de réduction/dépôt pour obtenir une suspension concentrée de poudre de cobalt contenant un dépôt de cobalt, dans laquelle le composant de cobalt est déposé, sous la forme d'une poudre de cobalt, sur la surface du matériau solide, par introduction de la suspension concentrée mélangée obtenue dans les tables de mélange dans un réacteur et réduction du cobalt contenu dans la suspension concentrée mélangée par soufflage d'un gaz d'hydrogène dans le réacteur; une étape de séparation solide-liquide pour obtenir le dépôt de cobalt et le liquide après la réduction par soumission de la suspension concentrée de poudre de cobalt obtenue dans l'étape de réduction/dépôt à une séparation solide-liquide.
