Abstract
SE REFIERE A UN METODO PARA SEPARAR CINC, EN ESPECIAL DE CONCENTRADOS DE SULFURO DE CINC DE BAJA LEY, DE MANERA QUE SE PUEDAN MINIMIZAR LOS COSTOS DE ENERGIA Y LOS DESPERDICIOS INUTILIZABLES; QUE COMPRENDE: 1) SOMETER EL CONCENTRADO A UNA ETAPA DE LIXIVIACION BIOLOGICA CON THIOBACILLUS FERROOXIDANS, LEPTOSPIRILLUM FERROOXIDANS, THIOBACILLUS THIOOXIDANS, SULFOBACILLUS Y OTROS; USANDOSE UN pH DE 0,5 A 2,5; UNA TEMPERATURA DE 20°C A 80°C; UN TIEMPO DE 0,5 DIAS A 10 DIAS Y CONDICIONES AEROBIAS; QUE SOLUBILIZA EL CINC, COBRE, CADMIO Y PARTE DEL HIERRO, MIENTRAS EL PLOMO, PLATA Y ORO PERMANECEN EN LOS SOLIDOS; 2) REMOVER EL CINC DE LA SOLUCION, USANDO UN DISOLVENTE ORGANICO DE EXTRACCION DE CINC; 3) RECICLAR POR LO MENOS PARTE DE LA SOLUCION DESPROVISTA DE CINC, LLEVANDOLA A LA ETAPA DE LIXIVIACION BIOLOGICAIT REFERS TO A METHOD FOR SEPARATING ZINC, ESPECIALLY FROM UNDER LAW ZINC SULFIDE CONCENTRATES, SO THAT USEFUL ENERGY COSTS AND WASTE CAN BE MINIMIZED; WHAT IT INCLUDES: 1) SUBMITTING THE CONCENTRATE TO A STAGE OF BIOLOGICAL LEACHING WITH THIOBACILLUS FERROOXIDANS, LEPTOSPIRILLUM FERROOXIDANS, THIOBACILLUS THIOOXIDANS, SULFOBACILLUS AND OTHERS; USING A pH OF 0.5 TO 2.5; A TEMPERATURE OF 20 ° C TO 80 ° C; A TIME OF 0.5 DAYS TO 10 DAYS AND AEROBIC CONDITIONS; WHICH SOLUBLIZES ZINC, COPPER, CADMIUM AND PART OF IRON, WHILE LEAD, SILVER AND GOLD REMAIN IN SOLIDS; 2) REMOVE THE ZINC FROM THE SOLUTION, USING AN ORGANIC SOLVENT FOR ZINC EXTRACTION; 3) RECYCLE AT LEAST PART OF CINC'S LOST SOLUTION, TAKING IT TO THE BIOLOGICAL LEACHING STAGE
