Latest Patents

Hansen holds a patent for an innovative "Induction slag reduction process for purifying metals." This patent details a continuous method for purifying and recovering transition metals like neodymium and zirconium, which can become reactive at elevated temperatures exceeding 500 degrees Celsius. The process involves contacting the metal ore with a fluorinating agent, such as an alkaline earth metal fluosilicate, to produce a fluometallic compound. The fluometallic compound is then reduced using a suitable alkaline earth or alkali metal compound under molten conditions, such as in an induction slag metal furnace. This method offers a simpler and cost-effective solution compared to previous techniques, and it accommodates a broader range of transition metals that were previously difficult to obtain in pure form due to reactivity issues.
