22-07-2019· First, mercury is mixed with the materials containing gold. A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is 100% pure, but it does eliminate the bulk of the impurities.

Amalgamation has forever and ever, thanks to mercury, been used to recover gold, fine gold in particular.

Mercury readily forms alloys with other metals, and this makes it useful in processing gold and silver. Much of the impetus to develop mercury ore deposits in the United States came after the discovery of gold and silver in California and other western states in the 1800s.

01-08-2017· 1. Introduction. The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006).After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leaching.

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). A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these ...

Gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. This process causes the gold to coagulate, and form nuggets and clumps of gold.
