Pilot scale studies were conducted by the Bureau of Mines on an electrooxidation technique for the extraction of mercury from cinnabar ores, particularly those that are too low in grade to be furnaced or retorted economically. Oxidation was accomplished by electrolysis of the ore slurried with brine. Recovery of 88 to 96 percent of the mercury as metal from cinnabar ores was shown to be feasible with the consumption of 17 to 60 kilowatt-hours of power per ton of ore and 22 to 92 pounds of salt per ton of ore.
