Abstract: The invention relates to a process for selectively and continuously extracting a series of desired species from a matrix, comprising the steps of:—injecting a plasma (310) in an extraction chamber by means of a plasma torch,—continuously monitoring (320) the excited elements extracted from the matrix and contained in the plasma by optical emission spectroscopy, and for each species of the series,—setting a distance (330) between the support and the plasma torch, and the composition of the injected plasma as a function of the monitored excited elements so that only one desired species of the series of species is being extracted from the matrix under molecular form, and—providing (400) a plate in the extraction chamber, exterior to the plasma, causing collection of molecules comprising said desired species by deposition onto the surface of the plate.

Abstract: An environmentally friendly (e.g. no acid, base, or cyanide) system and process for large scale extraction of metal ion into aerobic molten salt (or ionic liquid) and the electrodeposition of metal (e.g. copper, gold, silver, etc.) from the metal ion dissolved in the molten salt. The non-volatile low vapor pressure liquid salt is reusable, and heat from the molten slag can heat the molten salts or ionic liquids. Another embodiment comprises a one-pot apparatus for the extraction of metal (e.g. copper) from metal earths and electrodepositing the metal using a low melting (209° C.) aerated Na—K—Zn chloride salt in which copper metal oxidizes and is converted to soluble copper chloride. When an electrical power supply is connected to the graphite vessel (cathode) and to copper rods in the melt (anodes), then the copper chloride is deposited as copper metal by electroreduction on the bottom of the graphite reaction vessel.

Abstract: A method of reducing metal oxides in a plasma arc torch comprising a cathode and an anode. The method comprises collecting a set of metallic oxide ore and filtering the set of ore based on a particle size. The method further comprises preprocessing the filtered ore with the application of a heat gradient or an electric current. The preprocessed ore is mixed with a composition of reduction gases. The mixture is injected into the plasma arc torch to form a post-plasma mixture. The method further comprises collecting the post-plasma mixture and analyzing the post-plasma mixture. The method also comprises separating the post-plasma mixture into a set of slag and a set of liquid.

Abstract: This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s). Results include constituents formed in the liquid including micron-sized particles and/or nanoparticles (e.g., metallic-based nanoparticles) of novel size, shape, composition and properties present in a liquid.

Abstract: A method of producing a metal alloy utilizing aluminum smelter waste while simultaneously remediating the waste by converting the metallic and nonmetallic components to a non-hazardous slag. The method includes providing aluminum smelter, obtaining finely divided aluminum and/or spent pot liner from the aluminum smelter, and producing an alloy by oxidizing the finely divided aluminum and/or spent pot liner in the presence of nickelferous iron ore and heat. The non-hazardous slag is also produced during the process as a result of utilization of the nickelferous iron ore.
