Recuperación de oro de soluciones post-lixiviación con cianuro de sodio mediante cementación con cinc y adsorción en carbón activado

摘要

This study investigated the kinetics and loading capacity in the recovery of goldfrom cyanide solutions of a specific ore, considering the methods of zinccementation and adsorption on activated carbon. Studies were conducted withlaboratory-scale batch processes using a cyanide-leached solution with zincshavings and granular activated carbon. The kinetics of reaction with zinc wereanalyzed in time periods of 4 and 8 hours using the integral method of analysis,finding that the reaction order of gold is 1.
