New Materials, Compounds and Applications

The article is devoted to the study of sulfuric acid processing of serpentinites from the Karakalpak deposit with the aim of extracting magnesium and other valuable components. The work examines the main aspects of acid treatment, including the influence of various parameters such as temperature, duration of heat treatment, sulfuric acid concentration and rock grinding. The studies have shown that processing serpentinites with sulfuric acid can lead to the production of magnesium salts with a high yield in the liquid phase (up to 80%). Experimental results also demonstrated that heat treatment at 700-800 °C contributes to improved magnesium extraction from serpentinites. In addition, data were obtained on the fractional and elemental composition of serpentinites, as well as their thermal stability, which confirms the feasibility of using sulfuric acid decomposition for efficient extraction of magnesium and other valuable elements such as nickel and iron. The article proposes optimal process parameters that ensure maximum magnesium yield with minimal losses and favorable filtration characteristics.
