Moreover, various compounds that are formed naturally from iron ore such as iron chloride, iron hydroxide, iron sulfate, and iron arsenate
are anticipated to promote sizeable growth of the iron market over the conjecture period.
Using extended x-ray absorption fine structure spectroscopy, the research team was able to identify that the arsenic was contained in the mineral scorodite, an iron arsenate
. The finding means that the company can now make more accurate geochemical models, observing how the iron arsenate
behaves over time.
Despite the enormous amounts of iron and arsenic in the Bou Azzer district, the iron arsenate parasymplesite is fairly rare compared to its cobalt equivalent, erythrite.
In the district, secondary iron arsenates generally form at the expense of lollingite, arsenopyrite, safflorite and skutterudite.
Whereas jarosite and iron arsenates
are more abundant in the central part of the lens, copper minerals, especially copper carbonates and conichalcite, occur predominantly in the peripheral zone.
