Manganese is a critical metal for modern industry, essential in steelmaking and increasingly important for the production of advanced battery materials. As one of the world’s leading consumers and importers of manganese, China faces a persistent supply–demand imbalance, primarily due to the predominance of low-grade domestic resources that are highly impure and are further characterized by complex mineral textures and assemblages. This challenge is further exacerbated by surging demand from emerging sectors, particularly green energy technologies. This review systematically summarizes the current status of China’s manganese resources, focusing on their geological characteristics, genetic classifications, temporal and spatial distributions, and metallogenic belts. Recent advances in ore-forming theory and major breakthroughs in exploration over the past decade are critically reviewed, with emphasis on their implications for prospecting strategies and metallogenic models. The findings aim to guide future research directions and support strategic resource planning and industrial upgrading.

The experiments on the adsorption of Re(VII) onto Tributyl phosphate (TBP) coated solvent-impregnated LS-300 resins (TBP-CSIRs) were performed systematically. The optimal TBP concentration for the impregnation was 70%. The adsorption equilibrium reached in 6 h and the saturation adsorption capacity was 24.48 mg/g. The highest separation coefficients of rhenium over copper, iron, zinc, nickel, and arsenic were 93, 412, 348, 72 and 51, respectively. The adsorption capacity maintained in 93.50% after five times recycles. A 97.57% rhenium was recovered from waste acid with TBP-CSIRs, respectively. This study would contribute to the direct recovery of rhenium from waste acid.
