Title: Robin L Phinney: Innovator in Kaolin Refinement and Phosphoric Acid Production
Introduction
Robin L Phinney is a notable inventor based in Saskatoon, Canada. He has made significant contributions to the fields of mineral processing and chemical engineering. With a total of 3 patents, his work focuses on innovative processes that enhance the production of kaolin and phosphoric acid.
Latest Patents
One of his latest patents is a process for refining kaolin. This process is designed to produce high brightness kaolin from ore containing silica, various clays, and minerals such as ilmenite, micas, feldspars, and metal silicates. The method involves a series of steps including sizing, double flotation, magnetic separation, leaching, and oxidative brightening. This novel combination of conventional unit operations, particularly the double flotation step, effectively removes quartz and trace minerals that hinder the optical brightness of kaolin.
Another significant patent is an apparatus for producing phosphoric acid from phosphate ore. This invention outlines a method for recovering P₂O₅ from phosphate ore through a series of reaction zones. A slurry of phosphate ore is formed in an aqueous phosphoric acid solution, allowing for the efficient production of phosphoric acid while maintaining a differential concentration across the reaction zones.
