摘要： A gas injection device for introducing a process gas into a non-ferrous metal melt and/or slag, in particular a copper melt and/or copper slag, including a hollow-cylindrical lance which is formed from a refractory material and/or graphite, preferably includes a refractory material and/or graphite. The lance has an inlet opening for the process gas and a gas injection module connected to the hollow-cylindrical lance and formed from a refractory material and/or graphite, preferably including a refractory material and/or graphite, with at least one outlet opening for the process gas. The outlet opening includes at least one throughflow element formed from a ceramic material via which the process gas can be introduced into the melt.

摘要： 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).

摘要： 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carbon (C) is converted into a gas phase by the addition of an oxygen-containing gas, and the lithium and carbon are withdrawn from the process as discharge gas.

摘要： A method for obtaining non-ferrous metals, in particular black and/or raw copper, from scrap containing organic matter, comprises the following steps: i) providing a melting reactor, wherein the melting reactor includes a melting region, a combustion region and a pyrolysis region; ii) supplying the melting reactor with a mixture comprising the scrap such that it first passes through the pyrolysis region and the combustion region before it reaches the melting region, and is at least partially pre-pyrolyzed and/or combusted, such that an energy-containing gas stream is formed; iii) transferring the energy-containing gas stream into a thermal post-combustion chamber, in which the energy-containing gas stream is completely combusted and thermal energy released during combustion is carried off via an energy recovery unit; and iv) melting the scrap containing organic matter at least part of which has been pre-pyrolized and/or combusted.
