Apparatus for synergistically combining a plasma with a comminution means such as a fluid kinetic energy mill (jet mill), preferably in a single reactor and/or in a single process step is provided by the present invention. Within the apparatus of the invention potential energy is converted into kinetic energy and subsequently into angular momentum by means of wave energy, for comminuting, reacting and separation of feed materials. Methods of use of the apparatus in the practice of various processes are also provided by the present invention.
