Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
2015year8month12day The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.
