Abstract
PROCEDIMIENTO DE RECUPERACION DE CIANUROS DE LAS AGUAS DE LAVADURAS DE LOS PROCESOS CIANHIDRICOS DE ELECTRODEPOSICION DE METALES. CONSISTE EN PRECIPITAR LOS CIANUROS SOLUBLES CONTENIDOS EN LAS AGUAS ADICIONANDOSE CANTIDADES DE SALES METALICAS DE ACUERDO CON EL METAL LIGADO CON EL CIANURO. LA SAL SE EXTRAE DEL AGUA POR DECANTACION O FILTRACION. LOS METALES DE LAS SALES TIENEN UN PESO ATOMICO POR ENCIMA DE 60. PARA EL PROCESO SE EMPLEAN TANQUES DE LAVADURA SEPARADOS SIN QUE HAYA MEZCLA DE LOS METALES ENTRE SI. D
