Title: Innovations of Jon A Riesen

Introduction

Jon A Riesen is an accomplished inventor based in Albany, Oregon. He has made significant contributions to the field of materials processing, particularly in the separation of zirconium and petroleum coke. With a total of two patents to his name, Riesen's work showcases innovative methods that address complex challenges in material recovery.

Latest Patents

Riesen's latest patents include a method for separating coke from a feed mixture containing zirconium. This process involves grinding the feed mixture, slurrying it with water, and treating the slurry with a flotation agent and collector for the coke. The treated slurry undergoes air sparging and agitation to create an overflow and an underflow. The overflow is then filtered to collect substantially zircon-free coke for further processing. His second patent focuses on a zirconium-hafnium separation and purification process. This method recovers pure zirconium values from zircon sand, which also contains radioactive materials. The process includes chlorination, condensation, and separation stages to isolate zirconium and hafnium effectively.
