Frothers
Flotation Frothers for Controlled Performance
MetSoP provides a range of flotation frothers designed to control bubble size, froth stability and drainage.
The right frother can support mineral recovery, concentrate quality and efficient water management. Selection depends on the ore, circuit duty, water quality and required flotation performance.

The Role of Frothers in Flotation
Frothers help create and maintain the bubbles required to transport valuable minerals to the froth phase
Froth characteristics influence particle recovery, selectivity, water recovery and concentrate quality. The frother type and dosage must therefore be suited to the specific circuit conditions.
01
MetFroth 216
Alcohol based frothers developed for mobile froths, faster drainage and lower water recovery. These products are suited to applications where selectivity and concentrate quality are key priorities.
02
MetFroth 216
A balanced alcohol and glycol formulation developed for general flotation applications, including rougher and scavenger duties.
03
MetFroth 214
A glycol-based frother developed to provide smaller bubbles and more persistent froth characteristics. It may be suited to applications involving fine particles or challenging high sulphide ores.
Selecting the Right Frother
Frother selection requires a balance between recovery, selectivity and froth stability.
Our metallurgists consider:
- Ore and mineral characteristics
- Required recovery and concentrate grade
- Circuit position and flotation duty
- Particle size distribution
- Water quality and process conditions
- Frother interaction with other reagents
MetSoP can evaluate frother type and dosage through laboratory testing or on-site flotation optimisation.
