Consideration of the lunar environment suggests modifications of the Bayer-Hall approach leading to a conceptual process for extracting aluminum and oxygen from lunar soil. The process consists of electrowinning aluminum-silicon-iron-titanium alloy and oxygen from unrefined soil in a bipolar fluoride type cell with inert electrodes. Aluminum and other elements would be recovered from the alloy by vacuum fractional distillation. The silicon produced would be used to produce solar cells for additional electrical power.
