Fluorination processes

A method of producing an activated fluorination reagent from a waste stream comprising fluorine, the method comprising

• combining a waste material comprising a first salt comprising calcium and fluorine with a second salt, the second salt comprising an anion, which said anion when combined with Ca2+ to form a third salt has a lattice energy greater than 2450 KJ/mol, to form a salt-waste mixture;
• and
• applying mechanical force to the salt-waste mixture to yield the activated fluorination reagent.

A method of producing an activated fluorination reagent wherein <1 ppm of HF is produced, the method comprising

• combining a first salt comprising calcium and fluorine with a second salt, the second salt comprising an anion, which said anion when combined with Ca2+ to form a third salt has a lattice energy greater than 2450 KJ/mol, to form a salt mixture;
• and
• applying mechanical force to the salt mixture to yield the activated fluorination reagent.
