Summary

This paper investigates laser processing of lunar regolith simulants for metal extraction. Simulants EAC-1A, FJS-1, and JSC-2A are irradiated with a laser, leading to the extraction of K, Na, Fe, P, Si, and O. SEM/EDX analysis confirms the extraction. Surface temperatures reached 2823 K, aligning with oxide boiling points. The study suggests a multi-stage laser process for selective oxide extraction.
