Lixiviación de plata de minerales sulfurados argentíferos del complejo Marañón empleando el reactivo SANDIOSS

In order to study the metallurgical processes of the mineral from the Marañón mineralogical complex with polymetallic characteristics, the mineral was conditioned during the crushing process. Sodium bisulphite (NaHSO3), Cal, Zinc Sulfate (ZnSO4) were used as activating agents and depressants. ), Sodium cyanide (NaCN) and a granulometry of 62% -200 mesh was obtained; in the flotation, a bulk of Cu-Pb was first obtained using MIBC as foaming agent, to obtain a Zinc concentrate and obtain the flotation tailings, which was taken to a regrind to obtain an optimum granulometry for leaching, reaching work with a 96.5% -200 mesh and going to leach with Sandioss at two concentrations: 0.2 and 0.3% for a time of 75 hours, titrating with Silver Nitrate (AgNO3) and using a Potassium Iodide (KI) indicator, reaching obtain a recovery of 71.9% of Ag to 0.2% of Sandioss and 98.7% of Ag to 0.3% of Sandioss.
