In this process, due to the leaching of iron when in contact with water, iron (Fe 0) gets dissolved in the form of Fe 2+, and under the mild oxidising environment, Fe 2+ gets oxidised to Fe 3+ forming high oxidising intermediates which co-oxidises As(III) to As(V). Hence, As(III) gets oxidised without addition of chemical oxidant.
