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 of forming a metal material comprises exposing one or more metal oxide materials to one or more of a reducing agent and a reducing atmosphere to form one or more non-stoichiometric metal oxide materials and electrochemically reducing the one or more non-stoichiometric metal oxide materials to a metal material or a metal alloy. A system comprising one or more electrochemical cells and a working electrode comprising one or more non-stoichiometric metal oxide materials exhibiting an anion-deficient oxide structure is also disclosed, in addition to a metal material including a porous metal or a porous metal alloy that exhibits an oxygen content of less than or equal to about 1200 parts per million.

The above mentioned invention describes a process for producing uranium and/or at least one rare earth element selected from the group consisting of cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium and yttrium out of an ore. The ore is mixed with sulphuric acid with an concentration of at least 95 wt.-% to a mixture, wherein the mixture is granulated to pellets. The pellets are fed into at least one fluidized bed fluidized by a fluidizing gas for a thermal treatment at temperatures between 200 and 1000 C. The at least one fluidized bed is developed such that it at least partly surrounds a gas supply tube for a gas or a gas mixture fed into the reactor and the gas or gas mixture is used as a heat transfer medium.

Disclosed in the present application is a copper rotation-suspension smelting process comprising: mixing a flux and/or fume with dried copper-containing mineral powders to form a mixed material, which enters into a smelting furnace through a material channel; allowing a reaction gas to form a swirling flow under an action of a swirler, which enters into the smelting furnace through a Venturi channel under a guidance of a swirling gas channel; replenishing the reaction gas and/or a fuel to the smelting furnace through an auxiliary oxygen channel and an auxiliary fuel channel; subjecting the swirling flow which has been subjected to high-speed expansion through the Venturi channel and enters into the smelting furnace to a contact reaction with the mixed material; separating a melt generated by the reaction which falls into a settling tank into a residue layer and a copper-containing product layer.
