Hydrofluoric acid is one of the key pH modifiers used in flotation. It is used as an activator and depressant mostly in the flotation of industrial minerals eg. Tantalite, feldspar and silica

HF is widely used globally in the flotation of feldspar from quartz. It is used as an pH modifier to activate the feldspar whilst suppressing quartz. In this process, long chain amines are usually used as collector.

However, more often iron is normally found together with the feldspar. The iron and feldspar are then subjected to secondary flotation, also in HF but this time with another smaller chain amine collector.

Plant design should incorporate systems to recycle the water and avoid leakage of fluoride ions into the nearby streams.
