摘要
Process for the leaching of copper oxide without the utilization of sulphuric acid wherein it comprises impregnating said copper oxide using an organic non contaminant leaching agent which consists in a aqueous solution composed by tricarboxylic acid (C 6 H 8 0 7 ) in combination with water, in a mixture with an acidity varying between pH 1.0 to 5.0; obtain copper citrate; and optionally irrigates again said impregnated copper oxide with said organic non contaminant leaching agent, obtaining a copper citrate more concentrated.
