<p>The invention concerns a method for extracting a metal from a slag containing the metal, in which the liquefied metal-containing slag is heated in at least one arc furnace (1, 2). In order to develop an improved method for extracting, in particular, copper from slag, the invention provides for the metal-containing slag to be heated in a first furnace (1) in the form of an AC or DC electric furnace and for the melt from the first furnace (1) to be transferred to a second furnace (2) in the form of a DC electric furnace. The invention also concerns a device for extracting a metal from a slag containing the metal.</p> |
