Mercury Removal From Gold Ore Equipment

amalgam (chemistry) - wikipedia,crushed ore is washed over mercury-coated copper sheets, and fine gold particles form an amalgam with the mercury. the amalgam was scraped off and the gold then separated from the amalgam by heating and evaporating the mercury, which was then recovered by a condenser for reapplication to the plates..us4405588a - process of removing iron impurities from ores,a process of removing iron impurities from ores, particularly useful for removing stains of iron impurities adhered to silica sand particles, comprises grinding the ore, washing and desliming the ground ore to remove the major part of the clay-type binder, attrition-scrubbing the deslimed particles to release further amounts of binder therefrom, washing and desliming to remove said binder, drying and heating the ore.the historical use of the mercury mineral, cinnabar,amalgamation of poor quality silver ores using cinnabar was begun in mexico by bartolomé de medina in 1554. this process involved smelting the ore in grass-fired, clay-lined retorts until vaporization yielded gaseous mercury. some of the gas was trapped in a crude condenser, and cooled, yielding liquid mercury..the gold smelting process - melting, smelting & refining,to remove these traces of mercury from the gold you must heat it in a retort. the amalgamation process that employed mercury in the recovery of gold from the ore is no longer used at most major mines, but gold-rich ore often has some traces of mercury that may still stick to gold even after the precipitation and the leaching process. if not removed from the ore this mercury is likely to.
