    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.

    摘要： A process for depolymerizing fluoropolymers includes continuously feeding a solid fluoropolymer, in particulate form, into a horizontal cylindrical first reaction zone. The fluoropolymer particles enter the first reaction zone at one end. Within the first reaction zone, a central axle from which protrudes at least one paddle, continuously rotates. The rotating paddle serves to advance the fluoropolymer particles along the reaction zone while agitating them. As the fluoropolymer particles pass along the reaction zone, they are subjected to an elevated temperature, thereby depolymerizing the fluoropolymer into a fluoro-containing compound-rich gas phase. A residual solids phase is withdrawn at the other end of the first reaction zone, as is the gas phase. Optionally, the gas phase is passed through a second reaction zone which is also at an elevated temperature. The gas phase is quenched, thereby to recover the fluoro-containing compounds as gaseous products.
