Abstract

La invencion se refiere al uso de acidos debiles oxigenados o polioxigenados o minerales o compuestos que los generen, o de desechos solidos y liquidos de plantas productoras acidos debiles oxigenados o polioxigenados y sus derivados, para aumentar la recuperacion de cobre del mineral y/o para aumentar la concentracion de cobre de la solucion (PLS), en el proceso de lixiviacion o de biolixiviacion de cobre. Asimismo, se describe un procedimiento de lixiviacion y biolixiviacion, donde ambos procedimientos comprenden adicionar una cantidad necesaria de un acido debil oxigenado o polioxigenado, o un compuesto o un mineral que lo genere, a dichos procedimientos; y adicionar paralelamente acido sulfurico a las pilas de lixiviacion o biolixiviacionThe invention relates to the use of weak oxygenated or polyoxygenated acids or minerals or compounds that generate them, or of solid and liquid waste from plants producing weak oxygenated or polyoxygenated acids and their derivatives, to increase the recovery of copper from the mineral and / or to Increase the copper concentration of the solution (PLS), in the process of leaching or bioleaching of copper. Likewise, a leaching and bioleaching process is described, where both processes comprise adding a necessary amount of an oxygenated or polyoxygenated weak acid, or a compound or mineral that generates it, to said processes; and add sulfuric acid in parallel to the leaching or bioleaching heap
