Descripción:

The extraction and stripping of free cyanide and Fe, Zn, Cu cyano complexes from a waste solution of a Merrill Crowe process was studied. Anion exchange resins Amberlitre IRA 958, Amberlite IRA 900 and Amberlite 400 beads, packed in columns were used. The best extracting resin was Amberlite IRA 958 with a maximun loading capacity of 180 mg NaCN/ g of dry resin. Cyano complexes extraction was quantitative and inicial free cyanide was reduced to a 31 %.
