Abstract

Global critical minerals will highlight critical minerals such as lithium, cobalt, rare earth elements (REEs) and nickel that are critical in the clean energy transition. The analysis also covers the distribution of critical minerals in different regions of the world, including Europe, Africa, the Middle East, and Asia. It also discusses challenges in the extraction and processing of critical minerals and implications for sustainable exploration practices. The method used was a literature review of journals. The results show that countries such as Australia, the Democratic Republic of Congo, and China have significant critical mineral reserves. However, the African continent also has great potential in providing critical minerals needed for the clean energy transition. Therefore, emphasizing the importance of securing a reliable supply of critical minerals to support industrial and technological ambitions. In conclusion, then, with Australia, China, and Africa as major providers of clean energy, the provision of critical minerals such as nickel, lithium, cobalt, and REEs is essential for the clean energy transition and to control processes and reduce production costs, improve geological data and laboratory facilities for analysis are required. Indonesia has significant reserves for the global transition to clean energy and technological advancement. Hence, it is strategically positioned in the global mineral market as it becomes a focal point for geopolitical competition, especially between major powers. The regulatory framework in Indonesia can be complex and can pose challenges for foreign investment to enter, so addressing these challenges through increased research and regulatory alignment will be critical to unlocking Indonesia's abundant REE resources and meeting global demand.

Abstract

This research investigates ore samples from Cihaur Village, Sukabumi District, West Java, which exhibit significant skarn alteration in limestone, is examined for its petrographic and mineragraphic features. Secondary minerals identified include pyroxene, garnet, calcite, and opaque minerals, while the primary ore minerals are chalcopyrite (CuFeS2), galena (PbS), and sphalerite (ZnS). Five samples were analyzed geochemical analysis using the ICP-MS method to assess the concentration of important elements including Pb, Zn, Cu, Ag, Sb, Bi, Cd, Mg, Al, Ca, Fe, and As. Element distribution patterns were examined using spider diagrams, providing insight into environmental gradients influencing mineral exploration. The study revealed a high positive correlation between Pb and Zn, suggesting co-deposition in sulfide mineralization. Pb also correlates strongly with Ag and Sb. This study confirms the considerable economic potential of the Sukabumi skarn deposits for Pb, Zn, Cu, and precious metals such as Ag. Exploration value is increased when essential minerals like Sb and Cd are present. Variations in geochemical conditions indicate the influence of magmatic intrusions and hydrothermal activity on element distribution. These results provide a solid foundation for further exploration to delineate mineralization zones in the region
