Abstract
The growing significance of mineral processing processes in the contemporary mining and processing industry lies in their aim to augment the concentration of valuable constituents within processed natural raw materials. Predominantly, these processes encompass pyrometallurgy, hydrometallurgy, and electrometallurgy. Each method can extract nickel; however, the high energy demand of pyrometallurgy necessitates a shift toward refining the efficiency of hydrometallurgical procedures. Consequently, optimizing nickel-containing ore processing technologies to yield high-purity nickel and its compounds is a current research concern. This paper investigates the hydrometallurgical processing of nickel and cobalt via leaching, specifically targeting oxidized nickel-cobalt ore. Analytical studies reveal a promising potential for complex extraction of nickel and cobalt, achieving impressive yields of 98.4% and 90.7%, respectively. Our analysis further demonstrates that implementation of this method can notably elevate the extraction degree of targeted metals. Significant energy resource conservation is made possible by conducting extraction at a moderate temperature of 353K and at atmospheric pressure. Importantly, this approach facilitates the extraction of valuable components even from ores containing negligible concentrations. This scientific endeavor enhances our understanding of efficient, sustainable practices in the field of mineral processing, demonstrating the potential of hydrometallurgical methods for nickel and cobalt extraction.
