摘要： A process for treating a zirconium containing feedstock includes fluorinating a feedstock comprising dissociated zircon (‘DZ’) to obtain a zirconium fluorine compound and a silicon fluorine compound. The zirconium fluorine compound is separated from the silicon fluorine compound is provided. Optionally, the zirconium fluorine compound is reacted with a non-fluorine halogen, an alkali metal non-fluorine halide or an alkaline-earth metal non-fluorine halide, thereby to obtain a zirconium non-fluorine halide. The zirconium fluorine compound or, when present, the zirconium non-fluorine halide is subjected to plasma reduction, in a plasma reduction stage, in the presence of a reductant, to obtain metallic zirconium.
