Abstract

Processing apparatus and methods are provided which involve the selective ionization of a feed material; the separation of ionized and non-ionized species; a selective excitation of the still ionized species; introduction of a chemical material to cause selective transition to a non-ionized state of part of the feed; and a further separation of ionized and non-ionized species. Other improvements in selective excitation based processing are also disclosed. Separation of isotopes and/or elements from one another and changing chemical and physical form is provided in a single process from a variety of feeds.
