  • Additive for bioleaching that is substantially made up of the Licanantase lipoprotein, and bioleaching process to which this additive is added to increase the recovery of copper
    Patent number: 8728785
    Abstract: The invention discloses an additive for bioleaching that makes it possible to increase the recovery of copper from sulfide ores. In which this additive is substantially made up of the Licanantase lipoprotein and a solution of sulfuric acid with a pH of 0.8 to 3. The Licanantase lipoprotein that has an amino acid sequence with at least 50% homology regarding the sequence defined in SEQ ID No. 1 or is the product of translation of a nucleotide sequence with at least 50% homology regarding the sequence defined in SEQ ID No. 2. It also protects the improved bioleaching process that includes adding the additive during the ore bioleaching process as defined in the present invention; and continuing with the habitual process, obtaining copper recoveries increased 5 to 20%.
