Abstract
CARACTERIZADO PORQUE CONSISTE EN FUNDIR UNA CARGA DE PIRITAS Y/O ARSENOPIRITAS, CON CONTENIDO DE ORO Y PLATA, BAJO CONDICIONES REDUCTORAS (0,5% DE OXIGENO LIBRE) FORMANDO ASI PIRROTITA, QUE SE PONE EN CONTACTO CON PLOMO METALICOFUNDIDO A UNA TEMPERATURA DE 1100°C A 1200°C, DONDE AMBAS FASES EXISTEN EN ESTADO LIQUIDO, Y PERMITE QUE EL ORO Y LA PLATA SE TRANSLADEN DESDE LA PIRROTITA HACIA LA FASE DE PLOMO PARA UNA POSTERIOR GRANULACION Y ALMACENAMIENTO DE LA PIRROTITA; LUEGO LA FASE DE PLOMO ENRIQUECIDA ES SOMETIDA A UN PROCESO QUE ELIMINA LOS METALES PRECIOSOS, TAL COMO DESPLATADO CON ZINC, REGENERANDOSE LA FASE DE PLOMO Y OBTENIENDOSE POSTERIORMENTE LOS METALES PRECIOSOS. DICHO PROCESO TIENE COMO VENTAJA NO FORMAR COMO SUBPRODUCTOS OXIDOS GASEOSOS, DEBIDO A QUE OPERA EN AUSENCIA DE OXIGENOCHARACTERIZED BECAUSE IT CONSISTS OF MELTING A LOAD OF PIRITES AND / OR ARSENOPIRITES, WITH A GOLD AND SILVER CONTENT, UNDER REDUCING CONDITIONS (0.5% OF FREE OXYGEN), FORMING PIRORITE, WHICH IS IN CONTACT WITH A METALLIC FUSED 11 ° CA 1200 ° C, WHERE BOTH PHASES EXIST IN A LIQUID STATE, AND ALLOWS GOLD AND SILVER TO TRANSFER FROM THE PIRROTITE TO THE LEAD PHASE FOR A FURTHER GRANULATION AND STORAGE OF THE PIRROTITA; THEN THE ENRICHED LEAD PHASE IS SUBJECTED TO A PROCESS THAT ELIMINATES PRECIOUS METALS, SUCH AS ZINC DISPLACED, REGENERATING THE LEAD PHASE AND OBTAINING THE PRECIOUS METALS LATER. SUCH PROCESS HAS THE ADVANTAGE OF NOT FORMING GASEOUS OXIDES BY-PRODUCTS, BECAUSE IT OPERATES IN THE ABSENCE OF OXYGEN
