Froth Modifier (Polydodecanol Type)
Polydodecanol-type froth modifiers are used in flotation circuits to adjust froth stability, rheology, and transport properties without significantly affecting mineral selectivity. They reduce excessive froth viscosity in circuits processing clay-rich or talc-bearing ores, preventing froth overflow and concentrate losses. Froth modifiers are particularly valuable in platinum group metals (PGM) and nickel flotation where talc and other sheet silicates generate excessively stable, difficult-to-manage froths.
