Abstract

Procedimiento de recuperación de zinc a partir de partir de polvo de acería, en el que el polvo de acería se lixivia con una disolución de ClNa y CIH con pH: 3{< pH{< 4 originándose una disolución selectiva de cloruros de metales pesados que se filtra y cemento con polvo de Zn, procediéndose a una carbonatación de la disolución restante de cloruro de metales a la que se añade C0{sub,3 Na{sub,2 a una temperatura superior a 60ºC, originándose un precipitado de C0{sub,3 Zn, que se somete a calcinación, obteniéndose OZn. De aplicación en la metalurgia del zinc.
