Latest Patents

John B Snodgrass holds a patent for a method titled "Method for the recovery of fluorides from spent aluminum potlining." This patent outlines a process for recovering fluoride values from spent potlining and fluoride-containing insulating materials. The method involves reducing the materials to a fine particle size, incinerating them, and then leaching the ash residue with a dilute caustic. The leachate is treated with a calcium compound to precipitate calcium fluoride, which is then dried and treated with concentrated sulfuric acid to produce hydrogen fluoride gas and a metal sulfate. This innovative process not only recycles valuable materials but also results in an environmentally safe product suitable for landfill disposal.
