Beschreibung
Zusammenfassung:	The invention relates to processes for the detoxification of effluents from ore processing operations utilizing hydrogen peroxide. It has been found that the demand of hydrogen peroxide can be reduced considerably when a significant portion of magnetic substances contained in the effluent are being magnetially separated before treating the effluent utilizing hydrogen peroxide. The process of the invention can preferably be applied in the detoxification of tailings pulps which contain magnetic substances and cyanides.
