“…Various references report fluoride coprecipitation or adsorption with goethite. [12], [55] Both iron removal processes seem to provide a fluoride bleed, although practical application of such a treatment is not investigated. Furthermore, some considerations should be taken into account.…”

“…Thus, the goethite process is utilized to remove iron from leach liquors of pressure leaching of laterite. The goethite process usually requires that not only the Fe 3+ concentration in the solutions is below 1-2g/L , but also the solution pH is greater than 2 [6][7][8]. However, the pH of leach liquors from pressure leaching of laterite is about 1 or so.…”

Abstract. The leaching of laterite containing high-magnesium content was investigated in this study. The results show that the acidity of the leach liquors from high pressure leaching of laterite containing high iron content is high enough for the leaching of high-magnesium laterite. After leaching at 70˚C, 60min and solid/liquor ratio of 10g ore/L leaching agent, the mineral containing high magnesium content was completely dissolved, and the iron minerals were essentially undissolved. The solution pH increased to 2.5 or above, which was suitable for the subsequent iron removal process.

“…Le procédé goethite c'est l'un des procédés de traitement des résidus de lixiviation le plus utilisé pour la précipitation du fer sous la forme du filtrat. Ce traitement permet de dissoudre le zinc trouvé sous différentes formes de ferrite de zinc ou de ferrite complexe [3][4][5]. Ce travail traite la récupération du zincà partir des résidus de lixiviationà l'aide du procédé goethite.…”

Abstract. The present work has been conducted in the objective of valorising the zinc from leaching residues. For this purpose we have retained the goethite method which presented some advantages. The sulfuric acid concentration, temperature and time of treatment are those parameters chosen for this study. The effect of three selected parameters on dissolution of zinc from leaching residues was investigated. It is shown that when values parametric increases the content of zinc increase.Résumé.

La concentration d'acide sulfurique, la température et le temps de traitement ceux sont les paramètres choisis lors de ce travail. L'effet de trois paramètres sélectionnés sur la dissolution du zinc des résidus de lixiviation aétéétudié. Il est démontré que la teneur en zinc augmente avec l'augmentation des valeurs paramétriques.
