Abstract

UN PROCESO PARA RECUPERAR ORO Y PLATA DE MINERALES COMPLEJOS DE PIRITA Y ARSENOPIRITA. EL PROCESO IMPLICA LA FUSION DE LA PIRITA, LA OBTENCION DE PIRROTITA, EL CONTACTO DE UNA CAPA DE PIRROTITA FUNDIDA QUE CONTENGA UNA CANTIDAD DE METALES PRE- CIOSOS A SER RECUPERADOS CON UNA CAPA DE PLOMO FUNDIDO A UNA TEMPERATURA EN QUE AMBAS EXISTEN COMO FASES LIQUIDAS SEPARADAS, OBTENIENDO EL TRAS- LADO DE LOS METALES PRECIOSOS DE LA PIRROTITA AL PLOMO FUNDIDO. EL PROCESO ELIMINA TODA CANTIDAD SIGNIFICATIVA DE SUB-PRODUCTOS GASEOSOS OXIDADOS. FIGURA 1A PROCESS TO RECOVER GOLD AND SILVER FROM COMPLEX PIRITE AND ARSENOPYRITE MINERALS. THE PROCESS INVOLVES THE MELTING OF THE PYRITE, THE OBTAINING OF A PYRROTITE, THE CONTACT OF A LAYER OF MELTED PIRROTITE THAT CONTAINS A QUANTITY OF PRECIOUS METALS TO BE RECOVERED WITH A LAYER OF MELTED LEAD AT A TEMPERATURE IN WHICH BOTH EXIST AS FASES SEPARATED, OBTAINING THE TRANSFER OF PRECIOUS METALS FROM THE PIRROTITE TO THE MELTED LEAD. THE PROCESS ELIMINATES ALL SIGNIFICANT AMOUNTS OF OXIDIZED GASEOUS BY-PRODUCTS. FIGURE 1
