| Abstract: | The potential-pH diagram of the main equilibrium reactions for zinc oxide-water system at 298K and 373K have been constructed, and for zinc-water and iron-water system at 298K. With the help of the diagrams we have selected the reasonable technological condition on extracting cadmium and preparing zinc sulface from the zinc dust in thechimney of a zinc metallurgy factory. We have showed by production that the pHvalues selected were reasonable. |
