ABSTRACT:
A method is described for the precipitation by electrolysis of metallic mercury from an electrolyte containing Hg.sub.2 Cl.sub.2 in suspension by cathodic reduction.
The method includes an electrolysis cell containing Hg.sub.2 Cl.sub.2 in which chlorine developed at the anode during the course of oxidation can migrate without impediment to the cathode area of the cell. The electrolyte containing Hg.sub.2 Cl.sub.2 is subjected to electrolysis wherein chlorine is formed at the anode, chlorine reacts in situ with the Hg.sub.2 Cl.sub.2 to form HgCl.sub.2, and HgCl.sub.2 is reduced at the cathode to metallic mercury with the formation of chloride ions. The Hg.sub.2 Cl.sub.2 in the electrolyte is formed by oxidation of gaseous mercury with HgCl.sub.2, frequently when process gases are purified.
