These data include geochemical analyses of rock, mine waste, soil, sediment, and water samples collected from the Balkhab copper deposit, Sar-e Pol Province, Afghanistan in 2019.

This dataset contains X-ray diffraction (XRD) results for coal samples from the Usibelli Coal Mine and fly ash samples from the Atkinson Heat and Power Plant in Fairbanks, AK. Additionally, X-ray diffraction results from the solid phase residuals of leaching experiments with the same fly ash are reported. The leaching experiments were performed with either 18 mgea-ohm or simulated...

This data release contains the bulk chemistry and x-ray diffraction results of unreacted Alaskan stoker-boiler fly ash. X-ray diffraction results from the solid phase residuals of leaching experiments with the same fly ash are reported. The leaching experiments were performed with either 18 mega-ohm or simulated rainwater for up to 90 days and XRD was performed on solid phase residuals...

This dataset contains bulk chemical data for fly ash samples from the Atkinson Heat and Power Plant in Fairbanks, AK and National Institute for Standards and Technology (NIST) Standard Reference Materials (SRM) used for quality assurance and quality control.

Electron microprobe analyses of sphalerite (ZnS) were collected on samples from current or past mining operations in the USA with a specific focus on germanium (Ge), a byproduct critical mineral recovered from sphalerite. Data and methods reported are part of a research study published in the 'Related External Resources' section below.

Oxidation state and bonding environment of Ge and Cu in ZnS and Zn mineral concentrates from a variety of sources [Central Tennessee mining district (TN), Metaline mining district, (WA), and Red Dog mine (AK)] were determined by linear combination fits from x-ray absorption spectroscopy (XAS) analysis. Sphalerites from the East Tennessee mining district contained Ge in concentrations...
