Abstract

L'invention se rapporte au domaine du traitement des eaux usées et de la production de métaux nobles par le procédé au cyanure. Un procédé de traitement de pulpe de cyanure consiste à mélanger cette dernière avec du formaldéhyde tout en contrôlant constamment et en maintenant le potentiel des électrodes par rapport aux électrodes d'amalgame d'argent-chlorure d'argent dans la plage de -50 à -100 mV et à un pH de 8 à 11, après quoi une résine échangeuse d'ions est introduite dans la pulpe cyanurée.
