How Is Gold Extracted From Gold Ore? - SciencingMetals and Ores ~ Learning Geology

Another process involves ground ore being passed over plates which are coated with mercury The gold and the mercury form an amalgam, leading to the name of the process, amalgamation Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold The mercury gas is highly toxic and must be handled carefullyThe minerals in the cloud eventually sink and form a pile of ore minerals around the vent Since the ore minerals typically are sulphides, the resulting hydrothermal deposits constitute another type of massive-sulphide deposit Secondary-enrichment deposits Sometimes groundwater passes through ore-bearing rock long after the rock first formed.
