Abstract[English]
A froth transport system (100) and de-aeration apparatus (200) is disclosed. Each comprise a first holding tank or sump (201) and a froth pump (203) for transporting aerated slurry from the sump 201 to one or more hydrocyclones (204). Overflow of the one or more hydrocyclones (204) containing fines and gas (114) may be recycled to the first holding tank or sump (201), or back to an inlet manifold (206) feeding the one or more hydrocyclones (204). The froth transport system (100) and/or de- aeration apparatus (200) may comprise a second holding tank or sump (202). De- aerated slurry (106) may be transferred from the second holding tank or sump (202) to one or more centrifugal pumps (107) to move the same to a downstream process step (108).[French]
Un système de transport de mousse 100 et un appareil de désaération 200 sont divulgués. Chacun comprend un premier réservoir de rétention ou un premier puisard 201 et une pompe à mousse 203 pour transporter la boue aérée du puisard 201 à un ou plusieurs hydrocyclones 204. Le trop-plein du ou des hydrocyclones 204 contenant des fines et du gaz 114 peut être recyclé vers le premier réservoir de rétention ou le premier puisard 201, ou vers un collecteur d'entrée 206 alimentant le ou les hydrocyclones 204. Le système de transport de mousse 100 et/ou l'appareil de désaération 200 peuvent comprendre un second réservoir de rétention ou un second puisard 202. La boue désaérée 106 peut être transférée du second réservoir de rétention ou du second puisard 202 à une ou plusieurs pompes centrifuges 107 pour les déplacer vers une étape de traitement en aval 108.
