Title (EN) FROTH FLOTATION UNIT
(FR) UNITÉ DE FLOTTATION PAR MOUSSE
Abstract:
(EN) A froth flotation unit (10) for treating mineral ore particles suspended in slurry (1) is disclosed. The froth flotation unit comprises a tank (11), a gas supply for introducing flotation gas (2) into the slurry to form froth (3), and a first froth collection launder (21) comprising a first froth overflow lip (121a) facing towards the centre (111) of the tank (11). The froth flotation unit has a pulp area (A) of at least 15 m² measured at a mixing area (140). The froth flotation unit further comprises a second froth collection launder (22) with a first froth overflow lip (122a) facing the perimeter (110) of the flotation tank (11), and a froth blocker (31) arranged between the first froth overflow lip (121a) and the second froth overflow lip (122a). A froth flotation line, its use, and a froth flotation method are also disclosed.
(FR) L'invention concerne une unité de flottation par mousse servant à traiter des particules de minerai minéral en suspension dans une bouillie (1). L'unité de flottation par mousse comprend un réservoir (11), une alimentation en gaz pour l'introduction d'un gaz de flottation (2) dans la bouillie afin de permettre la formation de mousse (3) et une première goulotte de collecte de mousse (21) comprenant une première lèvre de trop-plein de mousse (121a) faisant face au centre (111) du réservoir (11). L'unité de flottation par mousse possède une zone de pulpe (A) d'au moins 15 m² mesurée au niveau d'une zone de mélange (140). L'unité de flottation par mousse comprend en outre une seconde goulotte de collecte de mousse (22) comprenant une première lèvre de trop-plein de mousse (122a) faisant face au périmètre (110) du réservoir de flottation (11), et un bloqueur de mousse (31) disposé entre la première lèvre de trop-plein de mousse (121a) et la seconde lèvre de trop-plein de mousse (122a). La présente invention concerne en outre une ligne de flottation par mousse, son utilisation et un procédé de flottation par mousse.
