These data represent the air-free pH and specific conductance per pore volume of effluent generated by the phosphate removal column experiment. Solid samples used for the columns are of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA.
These data represent the major, minor, and trace element compositions of effluent water samples generated by column experiments of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana. Details of the column experiments may be reviewed in the journal article listed in the cross-reference section of this data release titled, "Geochemical Characterization of Iron and Steel Slag and Its Potential to Remove Phosphate and Neutralize Acid".
The Ironwood Iron-Formation, part of the Gogebic Iron Range in Wisconsin, is a Paleoproterozoic Superior-type banded iron formation (BIF) with substantial iron resource potential. The development of a Mesoproterozoic contact metamorphic aureole related to the emplacement of the Mellen Intrusive Complex resulted in the production of a variety of silicate minerals in the western portion of the Ironwood Iron-Formation, including amphibole, pyroxene, and olivine. The presence of amphibole minerals, some of which occur in a fibrous habit, has complicated development of this resource due to potential human health impacts. This data release provides information related to amphibole and other minerals in order that commercial,...
Stable hydrogen (H), oxygen (O), and sulfur (S) isotope data were collected from the Elizabeth copper mine Superfund site, South Strafford, Vermont. Sample media include surface water (H and O), groundwater (H and O), dissolved sulfate (O and S), and sulfide minerals in bulk mill tailings samples. Where available, supporting data for water samples include discharge, pH, specific conductance, and dissolved sulfate concentration. The water samples span a time period from August 1998 to October 2009.

These data represent the acid neutralization potential and grain size analysis of 13 samples, 2 duplicate samples, of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA.
These data represent the major, minor, and trace element compositions of laboratory generated leachates of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA using USEPA method 1312 Synthetic Precipitation Leaching Procedure.
This dataset comprises photomicrographs from drill core and outcrop samples from the Ironwood Iron-Formation.
These data comprise chemical analyses in weight percent of oxides, as well as chlorine and fluorine, conducted using a JEOL JXA-8900 electron microprobe analyzer (EPMA) on amphiboles, pyroxenes, and carbonates in the Ironwood Iron-Formation.

This dataset comprises various energy-dispersive spectroscopy (EDS) analyses from drill core and outcrop samples in the Ironwood Iron-Formation, Gogebic Iron Range, Wisconsin, USA.
This worksheet displays the results of mineral abundance estimates based on Rietveld refinement of X-ray diffraction (XRD) analyses of mill tailings and other ore processing materials from worldwide localities. Data are also provided to show variation in mineral abundance estimates for subsplits in individual samples. Samples were analyzed using a PANalytical X'Pert Pro diffractometer using Cu radiation and the results interpreted using Highscore Plus v.4.7.
These data represent the phosphate removal capacity of modern and legacy iron and steel slag from the Chicago-Gary area of Illinois and Indiana, USA, based on batch leaching experiments. Also included are major, minor, and trace element compositions of the leachates along with associated water parameters pH, specific conductivity, and alkalinity. Details of the batch experiments may be reviewed in the journal article listed in the cross-reference section of this data release titled, "Geochemical Characterization of Iron and Steel Slag and Its Potential to Remove Phosphate and Neutralize Acid".
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...
