Title: Marc Murray Rishea: Innovator in Titanium Separation Technologies
Introduction
Marc Murray Rishea is a notable inventor based in Burlington, CA. He has made significant contributions to the field of titanium production through his innovative methods for separating titanium from ore. With a total of 2 patents, Rishea's work is pivotal in advancing titanium extraction technologies.
Latest Patents
Rishea's latest patents include two groundbreaking methods for the production of titanium metal from titanium-bearing ore. The first patent outlines a method that involves leaching the ore or a concentrate with an aqueous solution of a hydrogen halide. This process separates solids from the leach solution, resulting in a leachate solution. The leachate can then undergo extraction with an immiscible organic phase to selectively remove iron values, leading to high purity iron products. Additionally, titanium may be separated from the raffinate as TiO or through solvent extraction and thermal stripping. The preferred titanium halide in this method is titanium tetrachloride.
The second patent focuses on the separation of titanium halides from aqueous solutions. Similar to the first, this method also involves leaching the ore with an aqueous solution of a hydrogen halide and separating solids from the leach solution. The leachate solution is subjected to extraction with an immiscible organic phase, and titanium halide is separated from the organic phase by stripping, again favoring titanium tetrachloride.
Career Highlights
Throughout his career, Rishea has demonstrated a commitment to innovation in the field of materials science. His patents reflect a deep understanding of chemical processes and their applications in industrial settings.
