Lead the development and optimization of solvent extraction circuits for rare earth element separation from both primary and secondary sources
•
Design and execute bench- and pilot-scale experiments to evaluate separation efficiency, reagent performance, and system dynamics
•
Translate laboratory-scale successes into scalable, industrial processes with a focus on safety, sustainability, and cost-effectiveness
•
Own and evolve process flow diagrams (PFDs), mass balances, and P&IDs for solvent extraction systems
•
Drive selection and specification of extractants, diluents, and equipment (e.g., mixer-settlers, columns, or centrifugal contactors)
•
Analyze separation performance data to identify improvement opportunities and implement process changes
•
Collaborate closely with metallurgy, chemical engineering, and operations teams to support plant commissioning and troubleshooting
•
Author technical reports, scale-up plans, and design documentation to support commercialization of Phoenix Tailings’ extraction technologies
•
Stay at the forefront of solvent extraction technologies and rare earth processing trends to inform and elevate process strategy
Qualifications:
•
