The anion exchange resin Dowex 1X 4 Cl − in HCl medium could not be used to separate gold from iron in this kind of samples (iron ores) due to two reasons: the first one is that iron forms in HCl medium, the FeCl 4 − complex which adsorbs on the resin, and the second reason is that AuCl 4 − has stuck in the column and has never eluted. The following eluents have been used but without ...

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.
