Title: Marc Richer-Laflèche and Mineral Processing Innovations.
Introduction
Marc Richer-Laflèche is an inventor associated with Ste Foy, Canada, and Ressources Minieres Pro-or Inc. His patent work focuses on processing chromite products and recovering platinum group metals from ores and concentrates. He is credited with 2 patents.
Latest Patents
Richer-Laflèche’s listed patents address two related challenges in mineral processing: recovering valuable platinum group metals and improving the chrome-to-iron ratio of chromite products.
“Process for Recovering Platinum Group Metals from Ores and Concentrates” describes a method for treating chromite ore, chromite ore concentrate, or platinum group metal concentrate. The process mixes the feed with one or more salts, then contacts the mixture with gaseous chlorine and carbon monoxide at temperatures between about 240°C and 800°C. These steps convert at least one platinum group metal species into a chloride salt that can be recovered.
“Method for Increasing the Chrome to Iron Ratio of Chromites Products” describes a process for selectively chlorinating iron in chromite ore or concentrate. The material is mixed with salt and chlorinated in the presence of carbon monoxide at a temperature that promotes selective iron chlorination and forms a thin melt film around the chromite product. The resulting product has less iron and a higher chrome-to-iron ratio than the starting material.
Career Highlights
The patents reflect an emphasis on chemical methods for separating or modifying mineral components. By targeting platinum group metal recovery and selective iron removal, the inventions address processing steps relevant to the value and composition of chromite materials.
Collaborations
Richer-Laflèche is associated with Ressources Minieres Pro-or Inc. His listed coworker is Mario Bergeron.
Conclusion
Marc Richer-Laflèche’s patent portfolio centers on mineral-processing techniques that recover platinum group metals and improve the chrome-to-iron ratio of chromite products.
