METHOD FOR LEACHING COPPER OXIDE, REPLACING SULFURIC ACID WITH A NON-POLLUTING ORGANIC LEACHING AGENT |
摘要 |
<p>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.</p> |
