Lead Pyrometallurgical Process Engineer - High-Temp Refining

marianaminerals; Houston (TX); Sur place; USD 110 000 - 170 000; Plein temps

Résumé du poste

Mariana Minerals is seeking a highly motivated Pyrometallurgical Process Engineer to help build the critical minerals supply chain powering the world’s energy transition. You will lead the development and deployment of high-temperature refining and thermal processing systems, designing, modeling, scaling, and commissioning pyrometallurgical unit operations.

Collaborate with R&D, pilot plants, and software teams to automate workflows and optimize processes, with emphasis on safety, reliability,

Qualifications

• Strong foundation in chemical, metallurgical, or process engineering applicable to pyrometallurgical systems.
• Experience with equipment engineering and design, including brownfield modifications.
• Experience with EPC/EPCM firms supporting mining projects.
• Experience with pyrometallurgical mineral processing or metal refining.
• Experience with large-scale mining, critical-minerals processing, or battery-materials production.

Responsabilités

• Lead pyrometallurgical process scopes from early concept development through procurement, detailed engineering, fabrication, installation, commissioning, and ramp-up.
• Develop detailed heat and material balances for high-temperature process trains, including drying, calcination, roasting, reduction, smelting, converting, slag cleaning, refining, and off-gas treatment.
• Design and validate thermal process flowsheets and PFDs/P&IDs for pyrometallurgical circuits, ensuring safety, reliability, and scalability.
• Build first-principles thermodynamic and kinetic models for high-temperature reactors and furnaces to support scale-up and commercial deployment.
• Model and optimize phase equilibria, slag chemistry, metal recovery, refractory performance, and energy efficiency.
• Define specifications and operating envelopes for high-temperature process equipment, burners, power systems, refractory linings, and gas-handling systems.
• Identify, evaluate, and implement process improvements to maximize metal recovery, minimize energy consumption, control emissions, and ensure stable furnace operation under varying feedstock chemistries.
• Collaborate with R&D, lab teams, and pilot-plant engineers to translate bench- and pilot-scale findings into robust commercial pyrometallurgical designs.
• Work with environmental and controls teams to design and optimize off-gas handling systems.
• Partner with software and machine-learning teams to automate process-engineering workflows and develop advanced control, optimization, and digital-twin models for high-temperature reactors and furnaces.
