PHNX Materials
PHNX Materials is seeking a metallurgical engineer to develop and validate pilot-scale processes for recovering critical products from coal ash. The role involves process design, scale-up of extraction techniques, experimental validation, and analytical assessment to optimize yields and purity.
PHNX Materials is a clean-technology company that refines industrial waste streams — primarily landfilled coal ash — into critical materials for the semiconductor, building materials, and agriculture industries. The company extracts high-value metals and compounds including gallium, germanium, silicon, titanium, aluminum, and rare-earth elements from billions of tons of domestic industrial byproducts. PHNX aims to reduce U.S. reliance on foreign suppliers, particularly China, by reshoring domestic critical material supply chains essential to semiconductors, defense, and advanced manufacturing.
