Biooxidation of Arsenopyrite by Acidithiobacillus ferriphilus QBS 3 Exhibits Arsenic Resistance Under Extremely Acidic Bioleaching Conditions [PDF]
BiologyAs arsenopyrite is a typical arsenic-bearing sulfide ore, the biooxidation process of arsenopyrite is of great significance for the extraction of gold from arsenic-bearing gold ores and the generation of arsenic-bearing acid mine drainage.

Pyrite-promoted dissolution of arsenopyrite in the presence of Sulfobacillus thermosulfidooxidans
Journal of Materials Research and Technology, 2020 The weathering of arsenopyrite in mine wastes is crucial for the formation of arsenic-containing acid mine drainage (AMD). Arsenopyrite is always associated with pyrite.

Journal of Materials Research and Technology, 2020 Ferric iron has a significant effect on the bioleaching of arsenopyrite, the most efficient way for pretreatment of arsenopyrite-bearing gold ores. Up to date, the differential effect of Fe(III) compounds on that process was rarely studied. Herein, FeCl3,

Arsenic content in the lead flotation concentrate in dependence on NaCN dosage [PDF]
Mining and Metallurgy Engineering Bor, 2013 Flotation properties of arsenopyrite are similar to the flotation properties of pyrite. Specifically, in the alkaline conditions (pH value of pulp 7-11) and in the presence of xanthates as collectors, arsenopyrite can easily pass into concentrate ...
