Abstract: The invention relates to a method for leaching copper oxide without using sulfuric acid, comprising the following steps consisting in: impregnating the copper oxide using a non-polluting organic leaching agent consisting of an aqueous solution formed by tricarboxylic acid (C6H807) combined with water in a mixture having an acidity varying between a pH of 1 and 5; obtaining copper citrate; and, optionally, again irrigating the copper oxide impregnated with the non-polluting organic leaching agent, thereby obtaining a more concentrated copper citrate.
Abstract translation: 本发明涉及一种不使用硫酸浸出氧化铜的方法，包括以下步骤：使用由三羧酸（C6H807）与水组合形成的水溶液组成的无污染有机浸出剂浸渍氧化铜， 酸度在pH1和5之间变化的混合物; 获得柠檬酸铜; 并且可选地，再次冲洗浸渍有无污染有机浸出剂的氧化铜，从而获得更浓缩的柠檬酸铜。
