Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid 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.

The solubilization of uranium from a finely ground ore material was investigated in leaching tests each lasting for about 24 h. Ferric iron, added as Fe 2 (SO 4) 3 or produced by prior microbiological oxidation of FeSO 4, accelerated the rates of uranium leaching, as compared with those obtained with sulfuric acid or acidic ferrous sulfate.Pulp density and initial pH were also test variables.
