Title: Innovations of Roman Z Pyrih in Uranium Recovery
Introduction
Roman Z Pyrih is a notable inventor based in Golden, Colorado, recognized for his significant contributions to the field of uranium recovery. With a total of four patents to his name, Pyrih has developed innovative processes that enhance the efficiency of extracting uranium from phosphoric acid solutions.
Latest Patents
Among his latest patents, one stands out for its improvement in the process for recovering uranium from wet-process phosphoric acid. This invention utilizes two ion exchange liquid-liquid solvent extraction circuits. In the first circuit, uranium is reduced to the uranous form and recovered using a mixture of mono- and di-(alkyl-phenyl) esters of orthophosphoric acid. The process includes several steps, such as oxidatively stripping the uranium with phosphoric acid containing an oxidizing agent and recovering uranyl uranium from the strip solution. The improvements introduced by Pyrih include the removal of organics from the raffinate, the use of hydrogen peroxide as the oxidizing agent, and the regeneration of the alkali metal loaded agent before recycling it to the second circuit.
Another patent focuses on recovering uranyl uranium from solutions using a liquid-liquid solvent extraction agent. This process involves scrubbing the loaded agent with water and stripping it with ammonium carbonate solution. Pyrih's improvement in this patent includes using an alkali metal carbonate for stripping instead of ammonium carbonate and regenerating the solvent extraction agent with a mineral acid.
