Title: Paula J Bosserman: Innovator in Cerium Recovery
Introduction
Paula J Bosserman is a notable inventor based in Riverside, CA (US). She has made significant contributions to the field of cerium recovery, holding a total of 6 patents. Her innovative approaches have enhanced the efficiency of extracting cerium values from fluoride-containing ores.
Latest Patents
Among her latest patents is a method for the recovery of cerium from fluoride-containing ores such as bastnasite. This process involves grinding, roasting, and leaching the ore with dilute hydrochloric acid to produce an ore concentrate. The concentrate is then treated with a solution of hydrochloric acid and boric acid, which solubilizes cerium values and converts fluoride to tetrafluoroborate ion. The removal of tetrafluoroborate from the solution, often achieved through precipitation, is crucial as it prevents the loss of cerium as insoluble cerium tetrafluoroborate during further processing.
Career Highlights
Paula is currently associated with the Union Oil Company of California, where she continues to apply her expertise in innovative recovery methods. Her work has not only advanced the field but has also contributed to more sustainable practices in mineral extraction.
