RECOVERY OF COPPER FROM LOW-GRADE COPPER ORE USING ORGANIC ACID

This study aimed to investigate the effectiveness of organic acids, specifically citric acid and acetic acid, in extracting copper from low-grade copper ore. The experimental procedure involved leaching copper-containing samples with varying concentrations of the organic acids. Compared to acetic acid, citric acid had a better performance in copper oxide recovery. Also, the results of the experiments showed that the concentration of ۱ M citric acid had the highest recovery. The recovery of copper and copper oxide using citric acid at a concentration of ۱ M was ۷۷.۸% and ۸۸.۷% respectively.
