As the mostwidely produced metal after steel, aluminum is primarily sourced from bauxite. Based on bedrock types, bauxite deposits are classified into two main types: lateritic and karstic. The former represents the predominant bauxite mineralization type globally, accounting for 88% of total resources, while the latter is the primary bauxite mineralization type in China, constituting 95% of the national resource base. This paper summarizes research progress on bauxite in China, focusing on deposit distribution, metallogenic epochs, provenance, and genetic models. Since the implementation of recent prospecting breakthrough initiatives, continuous discoveries have been made in Shanxi, Guangxi, Guizhou, Henan, and other regions, cumulatively adding hundreds of millions of tons of bauxite resources. As the preferred target for expanding bauxite reserves in China, future efforts should address key issues such as the relationship between bauxite genesis and major geological events, the genetic mechanisms of diaspore, and the potential of associated critical metals. Additionally, research on aluminosilicate weathering and precipitation- related mineralization should be strengthened.
