Abstract
Un proceso de lixiviación por pilas mejorado para la lixiviación por pilas bacteriana de menas de sulfuros de metal base, caracterizándose el proceso por la adición de sulfuro elemental a la mena, donde las bacterias que oxidan el sulfuro, ingénitas o anadidas a la mena, pueden oxidar el sulfuro elemental y general calor al interior de la pila de la mena. Reivindicación 5: UN proceso de lixiviación por pilas mejorado para la lixiviación por pilas bacteriana de menas de sulfuros de metal base que contienen un mineral o un conjunto de minerales que requieren temperaturas mayores a 45s C para la oxidación eficiente del mineral o de cada uno de los minerales, caracterizándose el proceso por la adición de sulfuro elemental a la mena, donde el sulfuro elemental es oxidado a temperaturas menores de 45s C por bacterias mesofílicas presentes en la piula de la mena, generando esta oxidación del sulfuro elemental calor, y aumentando la temperatura interna de la pila en forma progresiva de manera tal que las bacterias termofílicas puedan operar.An improved battery leaching process for bacterial leaching of base metal sulfide ores, the process being characterized by the addition of elemental sulphide to the ore, where the sulfur oxidizing bacteria, innate or added to the ore, can oxidize elemental sulfide and general heat inside the ore pile. Claim 5: An improved battery leaching process for bacterial leaching of base metal sulphide ores containing a mineral or a set of minerals that require temperatures greater than 45s C for efficient oxidation of the ore or each of the minerals, the process being characterized by the addition of elemental sulfide to the ore, where the elemental sulfur is oxidized at temperatures below 45s C by mesophilic bacteria present in the ore pipe, generating this oxidation of the elemental sulfur heat, and increasing the internal temperature of the battery progressively so that thermophilic bacteria can operate.
