Abstract
SE REFIERE A UNA CEPA BACTERIANA AISLADA DE LA ESPECIE ACIDITHIOBACILLUS THIOOXIDANS DENOMINADA LICANANTAY, DEPOSITADA COMO DSM 17318 Y QUE UTILIZA COMPUESTOS DE AZUFRE REDUCIDO PARA SOSTENER EL CRECIMIENTO AUTOTROFICO. DICHA CEPA PRESENTA UNA ACTIVIDAD AUMENTADA EN LA LIXIVIACION DEL COBRE DE MENAS SULFURADAS MIXTAS, EN ESPECIAL LAS QUE CONTIENEN CALCOPIRITA, BORNITA, CALCOSINA, COVELINA, ENTRE OTRAS ESPECIES MINERALOGICAS DE COBRE. SE REFIERE TAMBIEN A UN PROCESO DE BIOLIXIVIACION DE MINERALES QUE CONSISTE EN LIXIVIAR LA MENA SULFURADA CON SOLUCIONES ACIDAS BACTERIANAS QUE CONTIENEN LA CEPA LICANANTAY DSM 17318 PARA LA OBTENCION DE COBRE, A UNA TEMPERATURA MENOR DE 35 ºC Y UN pH DE 1,0 A 2,5REFERS TO AN ISOLATED BACTERIAL STRAIN OF THE ACIDITHIOBACILLUS THIOOXIDANS SPECIES CALLED LICANANTAY, DEPOSITED AS DSM 17318 AND USING REDUCED SULFUR COMPOUNDS TO SUPPORT AUTOTROPHIC GROWTH. SAID STRAIN PRESENTS AN INCREASED ACTIVITY IN THE LEACHING OF COPPER FROM MIXED SULFURATED ORE, ESPECIALLY THOSE CONTAINING CHALCOPYRITE, BORNITE, CALCOSINE, COVELIN, AMONG OTHER MINERALOGICAL SPECIES OF COPPER. IT ALSO REFERS TO A MINERAL BIOLIXIVIATION PROCESS WHICH CONSISTS OF LEACHING SULFURATED ORE WITH BACTERIAL ACID SOLUTIONS CONTAINING THE LICANANTAY DSM 17318 STRAIN FOR THE OBTAINING OF COPPER, AT A TEMPERATURE LESS THAN 35 ºC AND A TEMPERATURE LESS THAN 35 ºC AND A TEMPERATURE LESS THAN 35 ºC ,5

Method to leach sulphide copper ores where the growth of microorganisms from the surface of the ores and in a leaching solution is inhibited and the pH of said solution is adjusted to 1.5 or less when leaching copper derived from sulphide ores that contain chalcopyrite.
