摘要： The present invention concerns a process for the recovery of metals and of heat from spent rechargeable batteries, in particular from spent Li-ion batteries containing relatively low amounts of cobalt. It has in particular been found that such cobalt-depleted Li-ion batteries can be processed on a copper smelter by: feeding a useful charge and slag formers to the smelter; adding heating and reducing agents; whereby at least part of the heating and/or reducing agents is replaced by Li-ion batteries containing one or more of metallic Fe, metallic Al, and carbon. Using spent LFP or LMO batteries as a feed on the Cu smelter, the production rate of Cu blister is increased, while the energy consumption from fossil sources is decreased.

摘要： A method of smelting aluminum from aluminum ore wherein the powdered ore is mixed with a flux containing substantial amounts of borax, sodium bicarbonate and a copper compound, preferably copper sulphate. The mixture is placed in a suitable vessel, preferably with a rounded bottom, that can withstand high temperatures and that has an outlet hole in the bottom. The mixture of powdered ore and flux is heated to a temperature sufficient to melt the mixture and thereby produce a molten material containing aluminum. The molten material is allowed to flow out of the outlet hole and to cool outside by means of air cooling which results in the aluminum separating out. Preferably, the flux comprises about one third borax, one third sodium bicarbonate and about one third copper sulphate. A suitable ore for this method is nepheline syenite.

摘要： An improved process is disclosed for carbothermically producing an alkaline earth metal aluminide from an aluminum-bearing material which, in one aspect comprises forming a mixture of a carbonaceous reducing agent and a slag comprising the aluminum-bearing material, the alkaline earth metal compound, forming, at a first temperature, an alloy containing impurities in the slag; removing the alloy containing the impurities from the slag; and then heating the slag to a higher temperature to form the alkaline earth metal aluminide. The alkaline earth metal compound used in the process may comprise calcium carbide. Alternatively, both the alkaline earth metal compound and the aluminum-bearing material may be obtained using a calcium aluminate slag such as a byproduct from the steel industry. The calcium aluminate slag is purified in a preliminary step to remove silicon by alloying it with iron and then removing a ferrosilicon alloy formed in this step. Byproducts formed during the reactions may be recycled back if desired.Either metallic aluminum, the alkaline earth metal, or both may be recovered from the aluminide material using, respectively a halide, a sulfurous, or a nitrogen stripping agent, or by reducing both metals in an electrolytic reduction cell. The alkaline earth metal aluminide may also be used as a reducing agent to recover other metals such as magnesium oxide by reduction from their respective compounds.

摘要： Highly corrosive molten or vaporous halometaliferous systems comprising metals and metal halides are confined by heat transferring walls on which a frozen layer of the highest melting component of the system is maintained as a protective coating. The confining walls are in essence composites which, in transverse cross-section, consist of a thermally conductive structural wall member having an adherent solid layer of the highest melting component of the confined system. The structural member is continuously cooled sufficiently to maintain its temperature below the melting point of the adhering solid layer. In one embodiment of the invention, the protected walls are employed as heat exchanging surfaces on which vaporous mixtures of metal halides and metal vapors are condensed.

摘要： The method for recovering lithium hydroxide from a lithium secondary battery allows a powder comprising lithium and valuable metals to be prepared from the lithium secondary battery. The powder is reduced to form a preliminary precursor mixture including a preliminary lithium precursor and valuable metal-containing particles. The preliminary precursor mixture is primarily washed with water (H2O) to generate a lithium precursor aqueous solution and a precipitate. The lithium precursor is recovered through solid-liquid separation of the lithium precursor aqueous solution and the precipitate. The lithium precursor is recovered, through additional washing and solid-liquid separation, from the precipitate obtained through the solid-liquid separation. A calcium compound is added in the primary washing operation or the additional washing operation. Therefore, a highly-pure lithium precursor can be obtained without a complex leaching process and additional processes resulting from a wet process of an acid solution.

摘要： The method introduces additives into flowing gas, fluid or fluidized media in a pulsed high pressure manner. The nozzle needle of at least one nozzle is variable and highly precisely moved for the introduction by means of a device and in such a way that additive is dosed exactly in relation to the volume flow of the medium. The pulsating additive stream is injected into the flowing medium by at least one well-aimed nozzle opening. The additives are dosed by means of a pressure that can be variably adjusted by pulse width and pulse frequency. The desired homogenous distribution is obtained by the penetrating injection jet.
