M33 - Conference paper at an international conference, printed in full
Sulphuric acid leaching of the ore sample from the MCM (Mauritanian Copper Mine) was carried out. The achieved leaching degree was ≤ 38%. To improve copper leachability from the ore, TG (thermogravimetric), DSC (differential scanning calorimetry, and DTA (analyses differential thermal analysis) were conducted on the ore, and XRD (X-ray diffraction) analysis was performed on the leach residue. Thermal analysis has shown that goethite quickly transforms to hematite at ≈ 300 °C. The XRD pattern reveals the presence of four main minerals in the leach residue of the ore sample. Among them, the goethite peaks are the most intense. It seems as if the decomposition of goethite (thermally or chemically) could be a cornerstone in increasing the copper leaching degree. Both pathways were checked, and in both cases, a significant increase in the leaching degree was achieved.
