Dispersion of sodium phytate on muscovite and the implications for arsenopyrite flotation [PDF]
, 2022 The effective flotation separation of sulfides and sliming silicate minerals is always a difficult problem. In this paper, the selective flotation of arsenopyrite from muscovite was studied by using sodium phytate (SP) as dispersant, and the mechanism ...

Microbially-induced separation of arsenopyrite and bioremediation of arsenic [PDF]
, 2009 This paper discusses the role of the mineral-adapted acidiphilic microorganism Acidithiobacillus ferrooxidans in the beneficiation of arsenopyrite-containing multisulfides (pyrite and chalcopyrite) and the bioremediation of the resulting arsenical waste ...

Instability of Antimony‐Based Energy Storage Materials in Alkaline Environments
ChemElectroChem, Volume 13, Issue 16, 18 August 2026.Antimony sulfide iodide (SbSI), antimony sulfide (Sb2S3), and antimony oxide (Sb2O3) rapidly degrade in alkaline electrolytes, forming potassium antimony sulfide oxide (PASO, K3SbS3·(Sb2O3)3) initially and dissolving during subsequent cycling. In contrast, SbSI shows improved structural stability in acidic media, highlighting the need to reconsider ...
