Mercury, Recovery by Electrooxidation.
Supplement Vol to Kirk-othmer Encyclo of Chem Tech Wiley & Sons NY 2D Ed PP 541-546 to:541-546
Electrolytic oxidation of cinnabar ores for mercury recovery was investigated. Oxidation was accomplished by the electrolysis of ore slurried with brine. Cinnabar was dissolved by oxidating the insoluble sulfide to soluble mercuric salts. The mercury ion in a brine solution forms a stable tetrachloro complex. Subsequent mercury recovery from leach solutions was readily accomplished by precipitation on zinc.
