Influence of pulp aeration on flotation separation of arsenopyrite from pyrite

, 2021
Data source: Yes, Upon request, contact author(s).Arsenopyrite, often associated with pyrite as the two most important hosts of gold in auriferous complex sulphide deposits, preferentially concentrates more gold than pyrite.

Microbially-induced separation of arsenopyrite and bioremediation of arsenic

, 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 ...

An XPS and XANES Study on the Bioleaching of Arsenopyrite with or without Pyrite

, 2017
In the present study, we investigated the bioleaching of arsenopyrite with or without pyrite by moderate thermophiles. In both chemical leaching and bioleaching, the addition of pyrite decreased the leaching rate of arsenopyrite.
