TREATMENT OF CHEMICAL FEEDSTOCKS Russian patent published in 2017 - IPC C22B34/14 B22F9/18 

FIELD: technological processes.

SUBSTANCE: invention relates to treating a zirconium containing feedstock. Method includes fluorinating a feedstock comprising dissociated zirconium, to obtain a zirconium fluorine compound and a silicon fluorine compound. Zirconium fluorine compound is separated from silicon fluoride compound. Method optionally includes reaction of zirconium fluorine compound with a halogen, alkali metal halide or alkali-earth metal halide to obtain zirconium halide. Method then includes plasma reduction of zirconium fluorine compound or, in case of presence thereof, zirconium halide in presence of a reducing agent to obtain zirconium metal.

EFFECT: method enables to produce nuclear-pure zirconium metal or zirconium metal with less rigid characteristics in terms of hafnium content; process is "dry", which enables to obtain less waste in comparison with a "wet" method.
