Modified Hydrometallurgical Approach for the Beneficiation of Copper from Its Low-Grade Ore.

ABSTRACT: This study describes a novel hydrometallurgical approach for efficient copper recovery from low-grade ores. Improvement in the copper extraction efficiency was explored by employing blends of acids (sulfuric acid and nitric acid) and an oxidizing agent along with exposure to microwave and ultraviolet radiation. Scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), X-ray diffraction (XRD), and optical microscopy (OM) were used to characterize the ores' elemental composition, morphology, and mineralogy, revealing the presence of wroewolfeite, chalcopyrite, and other mineral phases. Thermogravimetric analysis (TGA) investigated the thermal stability of the ore samples. Under optimal leaching conditions (liquid-solid ratio of 15:1 mL g^-1, copper ore parti
