• Hydrochloric Acid Leaching of Iron from Aluminous Clays

    Iron extraction increases with decreasing pulp density. This is due chiefly to the higher acid to clay ratios at lower pulp densities. The optimum concentration of sulfuric acid is 40%. More concentrated solutions of acid are not completely ionized, and consequently are less effective In Ion extraction.

    Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquidtosolid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

    Further increase in pulp density did not promote the leaching rate. Higher iron and sulfur content in the concentrate introduced a lag period, impairing leaching rates. Stepwise leaching was found to be more effective than starting at a 10% higher pulp density in the beginning itself. Most of the solubilized iron was in the form of ferric ions.
