Field quantification and characterisation of extreme arsenic …

Processing techniques involved the crushing, flotation, cya-nidation, and, most importantly, the roasting of the ore. The roasting broke down the sulfide phases thereby liberating the gold for subsequent leaching. A by-product of the roasting is arsenolite (AsIII 2O3

Evaluation of arsenic field test

Seven arsenic field test kits were evaluated for their ability to detect arsenic III, V, and a combination of species, and their performance was compared with that of graphite furnace atomic absorption spectrophotometry.

Field-scale bioremediation of arsenic-contaminated …

This research demonstrates that biogenic pyrite formed by stimulation of indigenous sulfate-reducing bacteria (SRB) in a natural aquifer can remove dissolved arsenic from contaminated groundwater under strongly reducing conditions. SRB metabolism led to the precipitation of biogenic pyrite nanoparticles capable of sorbing and co-precipitating arsenic. The field site is an industrial site where ...
