Abstract: The invention relates to a process for detoxifying cyanide- and/or cyanocomplex-containing aqueous solutions in the presence of heavy metals from the series consisting of Mn, Co, Ni, Cu, Cd, Zn, in particular Cu, by oxidative treatment of the solutions with a peroxide compound at pHs of 8 to 12, the peroxide compound used being an alkali metal percarbonate. The alkali metal percarbonate, preferably 2 Na2CO3 . 3 H2O2, is preferably added in solid form to the solutions to be detoxified. The process according to the invention, with respect to the use of peroxide compound, is significantly more effective than the previously known process using hydrogen peroxide.
