Almost all the phosphate apatite used in the world to produce phosphoric acid trough the wet process contains fluorine. When not properly controlled, this element creates process, health and environmental issues that can have dramatic impact. In recent year several technologies have been established or improved to tackle these challenges.

F absorption has been improved by simple changes that ensure a high efficiency while minimizing the CAPEX.

F usage has also been largely investigated to produce valuable product as AlF3 or HF but also easy to transport raw material as CaF2. This paper will describe some recent development related to these topics.
