Abstract

DONDE EL PROCEDIMIENTO COMPRENDE: a) MEZCLAR SIMULTANEAMENTE EL CONCENTRADO CON AGUA, CLORURO DE SODIO Y UNA SOLUCION DE CLORURO DE CALCIO EN AGUA EN UN EQUIPO MEZCLADOR; b) AGREGAR A LA SUSPENSION HOMOGENEA DE (a) ACIDO SULFURICO CONCENTRADO AL 96% EN PESO CON UN FLUJO CONTINUO Y A UNA VELOCIDAD TAL QUE NO SE APRECIEN SALPICADURAS Y SIN DEJAR DE REVOLVER LA SUSPENSION; c) AGREGAR DURANTE LA FORMACION DEL GEL REACTIVO CARBONATO DE CALCIO FINAMENTE MOLIDO EN UNA PROPORCION DE 0% A 6% EN PESO DEL CONCENTRADO SECO A TRATAR; d) DEPOSITAR EL GEL REACTIVO EN UNA POZA, UN CAJON O CUALQUIER RECIPIENTE SIMILAR Y DEJARLA EN REPOSO ENTRE 5 Y 60 DIAS; e) LAVAR LA MASA CONTENIDA EN LA POZA O EL RECIPIENTE CON UNA SOLUCION A UN FLUJO DE 20 A 200 L/m2*h DURANTE UN TIEMPO DE 5 A 50 DIAS; f) DESPUES DE DEJAR DRENAR, EL RESIDUO ES REGADO CON UN SOLVENTE TAL COMO PERCLOROETILENO PARA EXTRAER EL AZUFRE ELEMENTAL; Y, g) LUEGO DE REGAR CON SOLVENTE, EL SOLVENTE ES EVAPORADO PARA PRECIPITAR AZUFRE ELEMENTAL EN FORMA DE CRISTALES, Y LUEGO SE CONDENSA Y RECUPERA PARA SER REUTILIZADO, Y EL RESIDUO ES TRATADO PARA OBTENER ORO Y PLATA POR TECNICAS CONOCIDAS. EL CONCENTRADO CONTIENE ALGUNA O TODAS DE LO SIGUIENTE: CALCOSINA, DIGENITA, COVELINA, BORNITA, CALCOPIRITA Y ENARGITA. LA SOLUCION DE LAVADO ES AGUA PURA, AGUA INDUSTRIAL, AGUAS DE DESECHO TRATADAS, AGUA DE MAR, AGUA SALINA O SOLUCION DE REFINO DE EXTRACCION POR SOLVENTES
