Abstract

DONDE UNA PARTE DEL AGUA CONTENIDA EN LA SOLUCION ES AGUA LIMPIA (AGUA CORRIENTE, DE RIO, PURIFICADA O DESMINERALIZADA), Y LA OTRA PARTE ES AGUA RESIDUAL TRATADA (CLARIFICADA PARA ELIMINAR LOS SOLIDOS Y/O METALES PESADOS COMO EL ZINC) GENERADA DE UN PROCESO PARA LA EXTRACCION DE METALES NOBLES DE MINERALES QUE LOS CONTIENEN CON CIANURO; Y EL CIANURO METALICO ES UN CIANURO DE METAL ALCALINO O METAL ALCALINO TERREO, DE PREFERENCIA CIANURO DE Li, Na, K o Ca, EN UNA CANTIDAD ENTRE 0,001% Y 35% EN PESO EN BASE AL PESO TOTAL DE LA SOLUCION. EL pH DE LA SOLUCION OSCILA ENTRE 7 Y 13,5. EL PROCESO COMPRENDE: a) REACCION DE CIANURO DE HIDROGENO O GASES QUE LO CONTIENEN, CON UNA SOLUCION QUE CONTIENE AL MENOS UN HIDROXIDO METALICO Y/U OXIDO METALICO Y/U OXIDO MIXTO Y AGUA; b) DE CORRESPONDER, DILUCION CON AGUA DE LA SOLUCION OBTENIDA DE (a); SIENDO EL AGUA LA DESCRITA PARA LA SOLUCION. LOS METALES NOBLES SON ORO Y PLATA
