摘要： An alteration of the traditional zinc/zinc-amalgam reduction procedure which eliminates both the hazardous mercury and dangerous hydrogen gas generation. In order to avoid the presence of water and hydrated protons in the working solution, which can oxidize Eu2+ and cause hydrogen gas production, a process utilizing methanol as the process solvent is described. While methanol presents some flammability hazard in a radiological hot cell, it can be better managed and is less of a flammability hazard than hydrogen gas generation.

摘要： Metallic titanium is continuously produced in an electric-arc furnace under a vacuum by the metallothermic reduction of titanium tetrachloride by a reducing agent such as magnesium. The nanoparticles of titanium obtained from the reduction are simultaneously melted in a bath of molten titanium formed by the heat of an electric arc between a consumable titanium electrode and the molten titanium. A voltage applied across the electrode and the molten titanium is adjusted so that molten titanium is maintained in a cooled crystallizer during the entire process. The molten titanium solidifies on the top of a dummy bar that is drawn down as additional titanium is produced. Upon completion of each iterative reduction reaction, the vaporized reducing agent chloride is pumped out of the electric-arc furnace into a condenser using a vacuum pump. Then, additional reducing agent and titanium tetrachloride are added into the furnace, and the process is repeated.

摘要： The invention concerns a method for the continuous or discontinuous extraction of a metal or several metals from a slag that contains the metal or a compound of the metal, in which the liquefied metal-containing slag is heated in a primary or secondary smelting unit (1). To provide an improved method for extracting metals, especially copper, from slags, the invention provides that the metal-containing slag is heated in a primary or secondary smelting unit (1) designed as an alternating-current electric furnace, and the molten material is then fed from the primary or secondary smelting unit (1) into a furnace (2) designed as a direct-current electric furnace, in which the metal to be extracted is subjected to an electrolytic separation, where a reducing agent in the form of calcium silicide (CaSi), calcium carbide (CaC2), ferrosilicon (FeO), aluminum (Al), and/or reducing gases is added and/or injected into the primary or secondary smelting unit (1).
