The mining and ore processing of sulfide-bearing deposits generates large volumes of
waste rock (WR) and tailings, which often contain barren and residual iron sulfides (eg …

In this article, we provide a critical review on the occurrence, formation, structure and stability
of schwertmannite–an enigmatic Fe (III) oxyhydroxy-sulfate mineral that is of widespread …

Advanced argillic minerals, as defined, include alunite and anhydrite, aluminosilicates
(kaolinite, halloysite, dickite, pyrophyllite, andalusite, zunyite, and topaz), and diaspore. One …

Tailings generated during processing of sulfide ores represent a substantial risk to water
resources. The oxidation of sulfide minerals within tailings deposits can generate low-quality …
