Abstract

SE REFIERE A UN METODO PARA RECUPERAR COBRE Y ZINC A PARTIR DE UNA MATERIA PRIMA SULFIDICA, QUE COMPRENDE: A) LIXIVIAR EL MATERIAL DE SULFURO CON UNA SOLUCION DE CLORURO ALCALINO-CLORURO DE COBRE (II), DESPUES DE LO CUAL SE RECUPERA EL ZINC DE LA SOLUCION MEDIANTE LA EXTRACCION LIQUIDO-LIQUIDO, EN LA QUE EL pH DE LA ETAPA DE EXTRACCION SE REGULA A LA REGION 2-4 POR MEDIO DE UNA ALIMENTACION DE HIDROXIDO ALCALINO; B) PRECIPITAR EL COBRE, LUEGO DE LA PRECIPITACION, DESDE LA SOLUCION DE CLORURO DE COBRE (I), AGOTADA CON RESPECTO AL ZINC POR MEDIO DE UN HIDROXIDO ALCALINO EN FORMA DE OXIDO DE COBRE (I), QUE SE REDUCE A COBRE METALICOIT REFERS TO A METHOD TO RECOVER COPPER AND ZINC FROM A SULPHID RAW MATERIAL, WHICH INCLUDES: A) LEACHING THE SULFIDE MATERIAL WITH AN ALKALINE CHLORIDE-COPPER (II) CHLORIDE SOLUTION, AFTER WHICH ZIN IS RECOVERED OF THE SOLUTION BY MEANS OF LIQUID-LIQUID EXTRACTION, IN WHICH THE pH OF THE EXTRACTION STAGE IS REGULATED TO REGION 2-4 BY MEANS OF A FEEDING OF ALKALINE HYDROXIDE; B) PRECIPITATING COPPER, AFTER PRECIPITATION, FROM THE SOLUTION OF COPPER (I) CHLORIDE, EXHAUSTED WITH REGARD TO ZINC BY MEANS OF AN ALKALINE HYDROXIDE IN THE FORM OF COPPER OXIDE (I), WHICH IS REDUCED TO METALLIC COPPER
