Strategically critical metal germanium associated with coal measures is typically low in grade and highly dispersed. The co-occurrence of germanium with organic phases in coal measures poses great challenges to the leaching and separation/enrichment of germanium. To address this issue, this study conducted Fenton-nitric acid combined oxidative leaching of germanium associated with coal measures, developed selective functional materials for separating and enriching germanium from leachate, and systematically investigated the leaching and adsorption kinetic processes. The leaching efficiency of germanium associated with coal measures reached 79.37%, the capture efficiency of germanium from leachate exceeded 92%, and the comprehensive recovery rate of germanium associated with coal measures was above 73.02%. This dataset centers on experiments of low-acid solubilization transformation coupled with selective intensified separation and germanium extraction from germanium-bearing coal measures, and systematically collects key data from experiments on low-acid solubilization transformation of germanium-bearing coal measures and targeted separation of germanium from lignite leachate. The main contents include: composition analysis of germanium-rich lignite; oxidative leaching effects of germanium using nitric acid alone and the Fenton-nitric acid combination, leaching mechanism and kinetic rules of germanium in germanium-rich lignite; rules of simultaneous activation and depolymerization of humic acid in lignite; properties of targeted separation materials for germanium from leachate (including silica gel/tannic acid composite material, trihydroxy-functionalized titanium dioxide, and hydrotalcite-supported germanium ion-imprinted polymer) such as phase structure, surface functional groups, surface morphology and chemical composition, as well as their separation performance for germanium from leachate, kinetic and thermodynamic rules of the germanium adsorption process of the three types of separation materials, experimental data for verifying the cycling stability of the materials, and supporting materials including relevant academic papers and patent achievements. The data collection period spans from January 2022 to November 2025. The data collection locations include relevant laboratories of the School of Resources and Safety Engineering, School of Chemistry and Environmental Engineering at Wuhan Institute of Technology, and the School of Chemical Engineering at Zhengzhou University. For the germanium-containing liquid samples in static adsorption experiments, data was collected using a laboratory SHY-2AHS water bath constant temperature and constant speed shaker, and analyzed via standard procedures using a UV spectrophotometer (UV-3000) and inductively coupled plasma mass spectrometry (ICP-MS). All test procedures strictly follow relevant test specifications and operating protocols. The data is authentic, reliable, and exhibits good reproducibility. The total size of this dataset is 76.5 MB.
