Abstract
Lunar base construction demands in-situ resource utilization to avoid high transport costs. This study proposes a lunar-adaptable iron extraction process from ilmenite using mechanochemical treatment with CaCl22·2H2O, followed by acid leaching and electrodeposition. The mechanochemical treatment converts ilmenite into soluble salts, enabling efficient iron dissolution with hydrochloric acid and recovery condensed iron content by electrodeposition.
