Embodiments in accordance with the present disclosure are directed to methods and apparatuses used for extracting heavy rare gas. An example method includes passing inlet air through an airflow path of an apparatus, removing carbon dioxide and gaseous water from the inlet air, and cooling the inlet air to a threshold temperature while passing along the airflow path. The method further includes passing the cooled inlet air through an adsorption chamber of the apparatus to adsorb heavy rare gas from the cooled inlet air while the cooled inlet air is in a gaseous state, and extracting the heavy rare gas from the adsorption chamber.

Apparatuses and methods involving extraction of heavy rare gases

A system and method that includes flowing brine containing a metal ion through a reactor that includes porous particles having metal ion imprinted polymer having selective binding sites. The system and method further include discharging the brine from the reactor, contacting the porous particles with water, and pressurizing the reactor with carbon dioxide. The carbon dioxide reacts with the adsorbed metal ions to form a metal carbonate solution, where the metal carbonate solution can then be continuously purified with ion exchange. The method can include recycling eluent from the ion exchange back into the system for re-use. The method further includes depressurizing the reactor to precipitate metal carbonate from the metal carbonate solution and discharging the metal carbonate solution from the reactor.

In one embodiment, the present invention relates generally to a multi-stage system for performing melt coalescence and separation, the multi-stage system. In one embodiment, the multi-stage system includes a first container for mixing a powder with a salt, the first container having an opening, a heating means coupled to the first container for heating the first container and a second container coupled to the first container.

Multi-stage system for reaction and melt coalescence and separation

Aspects of the invention include methods for producing purified semiconductor or metallic materials. In one embodiment, the methods include admixing a particulate composition of a material, for instance, a metal, with a metal halide to produce a metal-metal halide admixture. The admixture is then heated to a temperature that is above the material's melting point in a container that is chemically and physically stable at that temperature. The molten admixture is allowed to segregate into a lower of the material and an layer of the metal halide and cooled. The metal halide is then separated from the material and a purified semiconductor or metallic material is thereby produced. Also provided are purified material crystals, shaped ingots and/or taper, sheet, or ribbons produced by such methods, as well as the silicon chips and solar panels in which such products are employed.
