Latest Patents

Pashley's notable patent focuses on the treatment of magnesium fluoride slag contaminated with metallic uranium or uranium compounds. The process involves digestion with potassium hydroxide, resulting in soluble potassium fluoride and insoluble magnesium hydroxide. The solid and liquid phases are then separated, and the solids are dissolved in acid to form a solution of metal salts. The liquid phase is treated with lime to precipitate calcium fluoride, allowing for the recycling of potassium back to the digestion reaction. This method efficiently removes uranium contamination while recovering magnesium for reuse or safe disposal, and produces calcium fluoride for various applications. He holds 1 patent for this innovative process.
