    Abstract: A separation and recovery method that enables titanium and tungsten to be separated and recovered from a used DeNOx catalyst in high yield. Specifically, a method of separating and recovering metal elements that includes a first heating step of heating a DeNOx catalyst containing titanium, tungsten, vanadium and iron in a chlorine atmosphere, thereby removing the vanadium and the iron from the DeNOx catalyst, and a second heating step, performed after the first heating step, of heating the DeNOx catalyst in a chlorine atmosphere while the catalyst is exposed to a gas of a hydrocarbon compound (excluding CH4) or an oxygen-containing carbon compound, thereby volatilizing the tungsten and the titanium from the DeNOx catalyst, and recovering the tungsten and the titanium from the DeNOx catalyst.

    Abstract: A method for producing a titanium-aluminum alloy containing less than about 15 wt. % aluminum, comprising: a first step in which an amount of titanium subchlorides at or in excess of a stoichiometric amount required to produce the titanium-aluminum alloy are reduced by aluminum to form a reaction mixture comprising elemental titanium, and then a second step in which the reaction mixture comprising elemental titanium is heated to form the titanium-aluminum alloy, whereby reaction kinetics of the method are controlled such that reactions resulting in formation of titanium aluminides are minimized.

    Abstract: A separation method of zirconium and hafnium according to an example of the present invention comprising, mixing step to prepare a crude liquid for extraction, by mixing a sulfuric acid solution including zirconium and hafnium, a catalyst, and an acidic extractant; and first extraction step to form a first extract solution layer comprising the acidic extractant in which the hafnium has been extracted and a sulfuric acid solution layer separated from the first extract solution layer, wherein the acidic extractant comprises any one selected from a group consisting of D2EHPA (Di-(2-ethylhexyl)phosphoric acid), PC88A (2-Ethylhexyl phosphonic acid mono-2-ethylhexyl ester), and a combination thereof. The separation method not only saves the amount of extractant used but also increases separation effect of zirconium and hafnium known to be difficult for separating each other, without using no toxic compound such as cyan.

    Abstract: A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the lesser of the boiling point of the alkali or alkaline earth metal at atmospheric pressure or the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.

    Abstract: A process for forming a salt, such as sodium tungstate, using a pyrometallurgical operation is provided. A slagging operation is performed in which a metal-containing material is melted in the presence of slag formers such as sodium metasilicate and silica. The metal predominantly reports to a denser metal-containing phase. The denser metal-containing phase may then be subjected to gas sparging with a carbon-containing gas in order to form metal carbide, preferably tungsten carbide.
