Finally, it will necessary to eliminate the mercury by distilling the gold amalgam (retorting), thereby

Cinnabar: The mercury mineral cinnabar: information and

Cinnabar is the chief mineral composed of the element mercury, and is a very important ore mineral. Though most Cinnabar is massive and uninteresting in habit, several localities produce phenomenal and strikingly colored red crystals that stand out with beautiful contrast on top of a white matrix. Cinnabar is occasionally associated with Native Mercury, in the form of small metallic blobs

Mercury (element)

Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm).
