Abstract
Procedeu pentru recuperarea cianurilor metalice, din solutiile rezultate la electrodepunerea metalelor, caracterizat prin aceea ca, în solutiile care contin o cianura complexa solubila a unui metal alcalin si a unui metal nealcalin reprezentat de Zn sau Cu, se adauga o sare solubila a aceluiasi metal nealcalin existent în solutie, care reactioneaza cu cianura complexa solubila si cu ceilalti ioni cian liberi care se afla în solutie, la pH cuprins între 1,5 si 4 de preferinta 2, formând o cianura insolubila a metalului sarii respective care precipita si se separa.
