			Flotation is largely an experimental science, which requires adaptations for every mine and separation plant. Flotation on Mars should work as on the Earth, although the lower gravity might have some influence and the availability of various additives might be limited. Flotation is effective for sulfates, and as sulfur is abundant on Mars, sulfated minerals may be common.
