A Review of Flotation Physical Froth Flow Modifiers
2.2. Froth Mobility, Stability, and Flotation Performance 2.2.1. Froth Stability Froth stability is defined as the ability of the bubbles in the froth to resist coalescence and bursting events [43]. It is regarded as the key driver of flotation performance, as it contributes to determining the grade and recovery of the flotation process [43 ...Web
Flotation Flowsheets
The flow-sheet is of the "secondary" type when flotation is an accessory or subordinate process and some other means of concentration, usually gravity concentration, is the principal method of treatment. On the basis of pulp routing, a flow-sheet is of the "concentrate-middling" type when the flotation feed pulp passes through a set of ...Web
