Abstract
L'invention concerne un système de traitement de minéraux (200, 300) comprenant un circuit de flottation (109), lequel système est caractérisé en ce qu'un circuit de broyage à sec précède le circuit de flottation (109). Le circuit de broyage à sec peut utiliser un broyeur à rouleaux verticaux (32) ou un broyeur à rouleaux (302), et au moins un dispositif de séparation de particules à air sec (201, 304, 307) positionné entre ledit broyeur à rouleaux verticaux (32) ou ledit broyeur à rouleaux (302) et le circuit de flottation (109). Le ou les dispositifs de séparation de particules à air sec (201, 304, 307) produisent un courant de fines sèches (38) et un courant grossier sec (202). Le courant grossier (202) est délivré au circuit de flottation (109) de façon à récupérer des métaux de valeur, tandis que le courant de fines sèches (38) contourne le circuit de flottation (109) et est combiné à des résidus déshydratés (116) dérivés du matériau (110, 111) quittant le circuit de flottation (109).
