Oxidation state and bonding environment of Ge in minerals within mine waste from sampled historical waste piles from the Tar Creek Superfund Site, Oklahoma, U.S. were determined by linear combination fits from x-ray absorption near edge spectroscopy (XANES) analysis. Ge content in quartz within these wastes was determined using XANES edge steps, and Ge content in sphalerite was compared using XANES edge steps versus electron microprobe analyses. Data and methods reported are part of a research study published here: White, S.J.O., Piatak, N.M., McAleer, R.J., Hayes. S.M., Seal, R.R. II, Schaider, L.A., Shine, J.P.

These data comprise various SEM images from drill cores and outcrops in the Ironwood Iron-Formation.
Steelmaking slag from near Chicago, USA, may be a viable option for treating phosphate-rich or acidic waters. Iron and steel slags from legacy and modern operations in the Chicago-Gary area of Illinois and Indiana, USA, are predominantly composed of Ca, Fe, and Si, with generally lesser amounts of Al, Mg, and Mn. Simulated weathering tests suggest that potentially deleterious elements such as Cr and Mn, present in significant concentrations in some samples, are generally hosted in insoluble phases making use in water treatment applications possible. However, generation of high pH and alkaline solutions may be an issue. Batch and flow-through column experiments document effective removal of phosphate from synthetic...

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.
These data include geochemical analyses of rock, mine waste, sediment, and soil samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2019. In addition, these data ​include geochemical analyses of water samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2019.
These data represent the major, minor, and trace element compositions of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA.
