In the catchment, high arsenic concentrations have been detected in various environmental compartments, due to the presence of arsenopyrite (AsFeS) mineralizations associated with gold ores in hydrothermal quartz veins [30].
Due to this reason, mineralogical composition in this study was adopted from the composition of Navajo Sandstone while assuming that arsenopyrite is the primary source of arsenic species in the ambient groundwater.
Even though there is sometimes no correlation between As and Au in the ore (in case of Mari Rosa deposit) (Ortega et al., 1996), arsenopyrite mineralization is always associated spatially depositing during another hydrothermal stage.
The TOZ occurs along the Porcupine-Destor Break within a zone of albitized sediments and strongly silicified felsic porphyries with associated pyrite and arsenopyrite mineralization.
As discussed later, the presence of the weathered, oxidized form of arsenopyrite (FeAsS) known as scorodite (FeAsO4<<2H2O), is critical to understanding local copper arsenic alloy production.
Biooxidation of arsenopyrite concentrates by Acidithiobaciiius ferrooxidans in shake flasks
We identified realgar in soils 1, 3, 4, and 11 and arsenopyrite in soils 4 and 7.
The firm will be operating induced polarisation studies on the northern arsenopyrite gold zone.
The mineralization is hosted in a wide and intense zone of biotite hornfels with abundant pyrite and arsenopyrite within Knob Hill Formation sediments (Table 1).
Strong alteration was encountered with zones of silicified and tourmaline-altered monzonite with stockwork quartz veins (up to 0.79 meters wide) and disseminated to massive arsenopyrite, chalcopyrite, pyrite, and rare pyrrhotite intersected in the majority of the holes.
