Abstract

L'invention porte sur un procédé de désulfuration et de désilification de bauxite par flottation selon lequel on effectue séquentiellement une flottation inverse pour la désulfuration et une flottation normale pour la désilicification. Pour la désulfuration, une bauxite de qualité moyenne ou médiocre contenant du soufre est soumise à une flottation inverse après un broyage de premier degré et pour la désilicification, le concentrat de désulfuration obtenu est soumis à une flottation normale après un nouveau broyage. Lors de la flottation inverse pour la désulfuration de la bauxite, on utilise de l'éthyl xanthate comme collecteur après le broyage de premier degré afin d'obtenir des mixtes de bauxite contenant du silicium. Après le broyage de second degré, les mixtes de bauxite sont soumis à une flottation normale pour la désilicification, au cours de laquelle on utilise un acide gras de saponification et un acide naphténique comme collecteurs, après mélange proportionnel de ces derniers. Le procédé de l'invention, qui permet de réduire le réactif utilisé et d'obtenir un concentrat de bauxite possédant un rapport alumine-silice compris entre 7 et 12 et contenant entre 0,1 et 0,5 % de soufre, répond aux exigences de production d'alumine à partir de bauxite du procédé Bayer.
