TL;DR: Molten Regolith Electrolysis is a main entry in the 外星矿物知识引擎 database.
Direct electrolysis of molten lunar regolith at 1600°C to simultaneously produce oxygen gas and metal alloy (Fe, Al, Si, Ti)
Method Type
Electrochemical
Input Material
Bulk lunar regolith (no beneficiation needed)
Output
O₂ gas + metal alloy ingot
Efficiency
Moderate - handles raw regolith but requires high temperature
Space Viability
Good - demonstrated by Metalysis/ESA; produces both O₂ and useful metals
