A system for using aqueous means for solubilizing chemical components contained in Sulphur type ore concentrate which may contain iron, cobalt, nickel, copper, platinum group metals and other metals considered valuable and of commercial interest, and a method of using the aqueous means for solubilizing such components is described.

A system includes a chamber comprising one or more openings and filled with an inert or reducing gas. The system includes a conductive material, at least one set of electrodes coupled to the conductive material, and a power supply configured to apply a voltage across the at least one set of electrodes to allow current to flow through and heat the conductive material. The system is configured to thermochemically reduce particulates by heating the particulates that are in electrical and/or thermal contact with the conductive material.

A method for beneficiation of mineralogical materials that comprises using a one or more of a suite of processes including fluidized bed separation, plasma-based stimulation or enhancement of chemical reactions using a Reactive X-Ray Chemical Processor, field enhancement of chemical reactions and process and drying. All of the processes can be used singly, jointly, simultaneously or sequentially in multiple stages. The methods are nearly non-polluting and serve to replace polluting wet chemistry and other beneficiation techniques.

A method for the electrolytic production of pure copper from copper-containing compounds dissolved in a high-temperature bath of molten salts which function as an electrolyte in an electrolytic cell. An electric current is passed between an anode immersed in the copper-ion rich molten salt bath and a cathode or cathode-lined kettle in which the molten salt bath is contained, thereby reducing the dissolved copper ions to form pure molten copper. The deposited molten copper collects at the bottom of the kettle and can be separated from the molten salt bath using conventional means.

The present invention relates to a process for the deoxidation of valve metal primary powders by means of reducing metals and/or metal hydrides, and a process for the production of tantalum powders that are suitable as anode material for electrolytic capacitors.
