Title (EN) ANALYSIS OF BUBBLES IN A PULP PHASE OF A FLOTATION CELL
(FR) ANALYSE DE BULLES DANS UNE PHASE DE PULPE D'UNE CELLULE DE FLOTTATION
Abstract:
(EN) A method and system for measuring properties of the pulp phase of a flotation cell are disclosed and includes at least partially submerging a probe inside the pulp phase of the flotation cell. The probe includes a camera, a light source and a viewing pane at an operative end of the probe. The viewing pane is positioned at an angle to the vertical and the camera is used to obtain intermittent images of the pulp phase through the viewing pane and under illumination from the light source.
(FR) L'invention concerne un procédé et un système pour mesurer des propriétés de la phase de pulpe d'une cellule de flottation et comprenant au moins l'immersion partielle d'une sonde à l'intérieur de la phase de pulpe de la cellule de flottation. La sonde comprend une caméra, une source lumineuse et un volet de visualisation à une extrémité fonctionnelle de la sonde. Le volet de visualisation est positionné à un angle par rapport à la verticale et la caméra est utilisée pour obtenir des images intermittentes de la phase de pulpe à travers le volet de visualisation et sous éclairage à partir de la source lumineuse.
