摘要： In the invention, cyanide-bearing gas scrubbing waters, which are produced in metallurgical processes, are cleaned. The same scrubbing water is circulated through all gas scrubbers (1, 3) essentially connected to the metallurgical process. The solid substance which is thus acquired in the scrubbing water is separated from the scrubbing water in a clarifier (4), wherefrom the extracted solid substance is conducted as pulp into the grinding circle of the process. The cyanide-bearing scrubbing water is further conducted into the cooling (9) of the material received from the metallurgical process smelting furnace. In the cooling (b 9), the major part of the cyanide is evaporized due to the rise in temperature.
