Sulphidic zinc concentrate usually also includes small amounts of rare metals such as indium and gallium. If the content of these metals in the raw material is sufficiently high, their recovery may be economically worthwhile. In the method according to the invention the recovery of indium and other desirable rare metals takes place in a zinc leaching process, in which at least part of the sulphidic concentrate is leached directly without roasting.

Le concentré de zinc sulfuré comprend généralement aussi de faibles quantités de métaux rares tel que l'indium et le gallium. Si la matière première brute contient une quantité suffisamment élevée de ces métaux, leur récupération est économiquement intéressante. Dans le procédé de l'invention, la récupération d'indium et d'autres métaux rares voulus est mise en oeuvre pendant un procédé de lixiviation du zinc, dans lequel au moins une partie du concentré sulfuré est lixivié directement sans grillage.
