Goethite Weathering Product Ore Iron

In the peroxide atmosphere weathering products are dominated by ferric sulfates and goethite a kinetic model was then developed for iron weathering in a water atmosphere using the shrinking core model scm this model includes competition between chemical reaction and diffusion of reactants through porous layers of secondary products.
