Title: The Innovative Contributions of Robert E. Sullivan
Introduction
Robert E. Sullivan is a notable inventor based in Louisville, KY (US). He is recognized for his significant contributions to the field of materials recovery, particularly in the extraction of gallium. His innovative approach has paved the way for advancements in the processing of materials.
Latest Patents
Sullivan holds a patent for a process titled "Process for recovering gallium." This invention provides a method for recovering gallium from calcined clay that has been leached with hydrochloric acid. The process involves treating the leach solution, which contains aluminum, ferric, and gallium chlorides, through ion exchange to first remove aluminum ions. Following this, the solution is treated to reduce ferric ions to ferrous ions. The reduced solution is then acidified with hydrochloric acid to ensure that gallium is present in the form of GaCl.sub.4 - ions. Finally, the solution undergoes another ion exchange treatment to separate the ferrous ions from the gallium, allowing for the ultimate recovery of gallium.
