Abstract: A method for treating molten metals (4) and/or slags in metallurgical baths comprises the introduction of a process gas into a melt bath. The process gas is accelerated to supersonic speed and is introduced below the melt bath surface (5) by means of at least one supersonic nozzle (6) with supersonic speed into the liquid phase of the molten metal (4) and/or into the slag and/or into the region of a phase boundary between molten metal and slag. The disclosure further relates to a metallurgical plant for treating molten metals.

Abstract: Lithium-containing electrochemical energy storage devices a recycled by the following steps: i) The electrochemical energy storage devices are initially comminuted and a fraction comprising an active material is separated from the comminuted material. The fraction includes carbon (C), lithium (Li) and at least one of cobalt (Co), manganese (Mn), nickel (Ni), or iron (Fe). ii) The fraction comprising active material is subsequently fed to a melt-down unit and is melted down in the presence of slag-forming agents so that a molten slag phase and a molten metal phase are formed, iii) Then, the lithium (Li) contained in the molten slag phase and/or molten metal phase is converted into a gas phase by the addition of a fluorinating agent and the carbon (C) is converted into a gas phase by the addition of an oxygen-containing gas, and the lithium and carbon are withdrawn from the process as discharge gas.

Abstract: The present disclosure relates to a method for the pyrometallurgical smelting of metal-containing raw materials, waste materials and/or secondary waste materials (M), wherein these are fed in shredded form to a smelting unit (1) which includes a smelting zone (6), a main reaction zone (7) and a secondary reaction zone (8) and are smelted in the presence of an oxidizing, reducing and/or inert gas and/or gas mixture (G), such that a liquid melt phase (9), a liquid slag phase (10) and a gas phase are formed. The oxidizing, reducing and/or inert gas and/or gas mixture (G) is supplied in compressed form via at least one injector (11) and is expanded adiabatically within the smelting unit (1) and is then injected as adiabatically expanded gas and/or gas mixture into the liquid slag phase (10).
