relatively low gold grades. Leaching processes, however, are not limited to such ores. The chlorination process, which is obsolete by now, used chlorine gas that was conducted through wet, precrushed gold ore forming soluble gold chloride that could be washed out with water. The dissolved gold was eventually precipitated from the aqueous
