Bio-metallurgical process in which bio-oxidation of mineral compounds is produced

摘要

The present invention relates to a process for bio-oxidating insoluble mineral compounds from ores comprising the steps of: a) conditioning the ore with an acidic solution; b) adding a microbial inoculum to the conditioned ore; c) drying the ore until soluble bio-oxidized products in solid state are obtained, the solid products containing microbial colonies; d) maintaining the ore into an adequate range of temperature for the employed microorganism, until the bio-oxidation is completed; and e) separating out the soluble bio-oxidized products in solid state by washing or by another suitable method.
