Separation of Lunar Ilmenite: Basalt vs. Regolith

K. A. DeLa’o, T.C. Eisele, D. B. Kasul, William I. Rose, S. Komar Kawatra

Abstract

The paper presents the advantages and disadvantages of using lunar basalt or regolith as feedstock for an ilmenite extraction scheme. The ilmenite on the lunar surface is more reduced than ilmenite found on earth, hence, separation practices followed on earth cannot be used on the moon. The paper critically examines methods of ilmenite extraction on the lunar surface.
