Massive and ambitious underground space development projects are being undertaken by
many countries around the world to decongest megacities, improve the urban landscapes …

Amongst various metal chalcogenides, CuS (copper sulfides) have been widely explored in
past years due to its semiconducting behavior and non-toxic nature. CuS owns remarkable …

Acid mine drainage (AMD) formation and toxic arsenic (As) pollution are serious
environmental problems encountered worldwide. In this study, we investigated the crucial …

The extraction of mineral resources requires access through underground workings, or open
pit operations, or through drillholes for solution mining. Additionally, mineral processing can …

Pyrite is the earth's most abundant sulfide mineral. Its frequent undesirable association with
minerals of economic value such as sphalerite, chalcopyrite and galena, and precious …

Abstract Neutrophilic Fe-oxidizing bacteria (FeOB) are often identified by their distinctive
morphologies, such as the extracellular twisted ribbon-like stalks formed by Gallionella …

Pyrite, FeS2, commonly referred to as “Fool's gold” is the most common sulfide in the Earth's
surface region. Not only is the mineral ubiquitous, but the reactivity of pyrite is of central …

The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using
selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually …

Antimony (Sb) is an element of growing interest, and its toxicity and mobility are strongly
influenced by redox processes. Sb (III) oxidation mechanisms in pyrite suspensions were …

The search for affordable high performance electrode materials in photoelectrochemical
hydrogen production by solar water splitting is an ongoing quest. Hematite is a photoanode …
