Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA RECUPERAR ZINC DE MINERALES O CONCENTRADOS QUE CONTENGAN ESFALERITA, POR EL CUAL, EN UN PRIMER PASO, ESTOS MINERALES O CONCENTRADOS SE SOMETEN A TRATAMIENTO TERMICO PARA CONVERTIR LA ESFALERITA EN UNA SUSTANCIA QUE SEA ATACADA MAS FACILMENTE EN MEDIOS HIDROMETALURGICOS Y, EN UN SEGUNDO PASO, SE SOMETE DICHA SUSTANCIA A LIXIVIACION, CON LO CUAL DICHO TRATAMIENTO TERMICO CONSISTE ESENCIALMENTE EN UN CICLO DE CALENTAMIENTO REALIZADO EN CONDICIONES QUE HACEN QUE LA ESFALERITA SE TRANSFORME, AL MENOS PARCIALMENTE, EN WURTZITA, Y EN UN CICLO DE ENFRIAMIENTO RAPIDO, REALIZADO EN CONDICIONES QUE HAGAN QUE SE MANTENGA ESTA WURTZITA, AL MENOS PARCIALMENTE, A BAJA TEMPERATURA.
