Abstract

REFERIDA A UN PROCEDIMIENTO DE LIXIVIADO QUE COMPRENDE HACER PASAR UN MATERIAL RESIDUAL QUE CONTIENE METAL DESDE UNA OPERACION DE PROCESAMIENTO DE MINERAL HASTA UNA ETAPA DE LIXIVIADO BIOLOGICO, EN EL QUE UNA PROPORCION DEL METAL SE EXTRAE EN UNA SOLUCION DE LIXIVIADO CARGADA (PLS) Y LUEGO HACER PASAR LA PLS A UNA RECUPERACION DE METALES AGUAS ABAJO, DONDE EL MATERIAL RESIDUAL QUE CONTIENE METAL ES PRODUCTO DE UNA ETAPA DE CONCENTRACION QUE CONSISTE EN UNA ETAPA DE FLOTACION DE ESPUMAREFERRING TO A LEACHING PROCEDURE THAT INCLUDES PASSING A RESIDUAL MATERIAL CONTAINING METAL FROM A MINERAL PROCESSING OPERATION TO A BIOLOGICAL LEACHING STAGE, IN WHICH A PROPORTION OF THE METAL IS EXTRACTED IN A SOLUTION OF LEACHAGE AND THEN LOADED MAKE THE PLS GO TO A DOWNWATER METAL RECOVERY, WHERE THE RESIDUAL MATERIAL CONTAINING METAL IS THE PRODUCT OF A CONCENTRATION STAGE THAT CONSISTS OF A FOAM FLOTATION STAGE
