The mobility of Ca increased with the limestone doses, which was expected, as this element is decifrando a terra wilson teixeira major constituent of the neutralizing agents applied to the columns. The experiment was conducted in PVC leaching columns diameter 0. These results can be ascribed to the formation of geochemical barriers due to the precipitation of iron hydroxides on the surface of the sulfides in the sterile.
