Latest Patents

Havenga holds a patent for a process titled "Treatment of Chemical Feedstocks." This patent describes a method for treating a zirconium-containing feedstock that involves fluorinating a feedstock comprising dissociated zircon (DZ) to obtain a zirconium fluorine compound and a silicon fluorine compound. The process includes the separation of the zirconium fluorine compound from the silicon fluorine compound. Additionally, the zirconium fluorine compound can be reacted with a non-fluorine halogen or halides to produce a zirconium non-fluorine halide. The zirconium fluorine compound, or the zirconium non-fluorine halide, is then subjected to plasma reduction in the presence of a reductant to obtain metallic zirconium. This innovative process has the potential to enhance the efficiency of zirconium extraction and processing.
