Abstract

The invention relates to a method for extracting non-ferrous metals, especially zinc, from raw materials containing metal by means of electrolysis using a technique which is known in itself. According to the inventive method, substances containing phosphor are also added. This both facilitates the precipitation of toxic electrolysis substances and improves the current efficiency during the electrolysis.
