AbstractCritical Minerals underlies our economic prosperity, national defense security and technological leap. It supports the stable and vigorous development of China' s strategic emerging industries (clean energy industry and photovoltaic solar industry) as important metal raw materials. Major developed economies in the world have carried out the evaluation of critical mineral resources, and formulated corresponding development strategies for them. The evaluation method related to critical minerals has gradually developed from one-dimensional to multi-dimensional, and the factors both environment and recycling rate are considered as evaluation indicators. Indium was discovered in 1863 by Ferdinand Reich and Hieronymus Theodor Richter at the Freiberg School of Mines, Saxony, Germany. Now, it is an indispensable key mineral resource for world economic development in high-tech application fields such as semiconductors, solar cells and display devices like LCDS. Indium occurs mainly in deposits which related to zinc, copper and tin, and is recovered as a by-product in the process of zinc smelting. It is generally easy to enrich in the late stage of magmatic crystallization, but it is also highly enriched in some mafic rocks, showing the dual geochemical nature. Comprehensive evaluation of indium enrichment in different geological bodies is the main way to solve the safety and stability supply of indium resources in the future. SEDEX and VMS deposits may become the main sources for indium in the next few years. Abnormal enrichment of indium in volcanic rocks should be paid enough attention. The main carrier mineral for indium is sulfide such as sphalerite. In different types of ores, the enrichment of indium is selective to typical minerals, e. g. cassiterite, sphalerite, chalcopyrite, pyrrhotite. The mechanism of indium selective super-enrichment (such as indium window and indium explosion) is a key scientific issue in the study of indium mineralization in the future, and the breakthrough of in-situ quantitative analysis technology is the key to solve this key problem.
